A is an M-by-N - matrix which may be rank-deficient. - - Several right hand side vectors b and solution vectors x can be - handled in a single call; they are stored as the columns of the - M-by-NRHS right hand side matrix B and the N-by-NRHS solution - matrix X. - - The problem is solved in three steps: - (1) Reduce the coefficient matrix A to bidiagonal form with - Householder tranformations, reducing the original problem - into a "bidiagonal least squares problem" (BLS) - (2) Solve the BLS using a divide and conquer approach. - (3) Apply back all the Householder tranformations to solve - the original least squares problem. - - The effective rank of A is determined by treating as zero those - singular values which are less than RCOND times the largest singular - value. - - The divide and conquer algorithm makes very mild assumptions about - floating point arithmetic. It will work on machines with a guard - digit in add/subtract, or on those binary machines without guard - digits which subtract like the Cray X-MP, Cray Y-MP, Cray C-90, or - Cray-2. It could conceivably fail on hexadecimal or decimal machines - without guard digits, but we know of none. - - Arguments - ========= - - M (input) INTEGER - The number of rows of the matrix A. M >= 0. - - N (input) INTEGER - The number of columns of the matrix A. N >= 0. - - NRHS (input) INTEGER - The number of right hand sides, i.e., the number of columns - of the matrices B and X. NRHS >= 0. - - A (input/output) COMPLEX array, dimension (LDA,N) - On entry, the M-by-N matrix A. - On exit, A has been destroyed. - - LDA (input) INTEGER - The leading dimension of the array A. LDA >= max(1,M). - - B (input/output) COMPLEX array, dimension (LDB,NRHS) - On entry, the M-by-NRHS right hand side matrix B. - On exit, B is overwritten by the N-by-NRHS solution matrix X. - If m >= n and RANK = n, the residual sum-of-squares for - the solution in the i-th column is given by the sum of - squares of elements n+1:m in that column. - - LDB (input) INTEGER - The leading dimension of the array B. LDB >= max(1,M,N). - - S (output) REAL array, dimension (min(M,N)) - The singular values of A in decreasing order. - The condition number of A in the 2-norm = S(1)/S(min(m,n)). - - RCOND (input) REAL - RCOND is used to determine the effective rank of A. - Singular values S(i) <= RCOND*S(1) are treated as zero. - If RCOND < 0, machine precision is used instead. - - RANK (output) INTEGER - The effective rank of A, i.e., the number of singular values - which are greater than RCOND*S(1). - - WORK (workspace/output) COMPLEX array, dimension (LWORK) - On exit, if INFO = 0, WORK(1) returns the optimal LWORK. - - LWORK (input) INTEGER - The dimension of the array WORK. LWORK must be at least 1. - The exact minimum amount of workspace needed depends on M, - N and NRHS. As long as LWORK is at least - 2 * N + N * NRHS - if M is greater than or equal to N or - 2 * M + M * NRHS - if M is less than N, the code will execute correctly. - For good performance, LWORK should generally be larger. - - If LWORK = -1, then a workspace query is assumed; the routine - only calculates the optimal size of the WORK array, returns - this value as the first entry of the WORK array, and no error - message related to LWORK is issued by XERBLA. - - - RWORK (workspace) REAL array, dimension at least - 10*N + 2*N*SMLSIZ + 8*N*NLVL + 3*SMLSIZ*NRHS + - (SMLSIZ+1)**2 - if M is greater than or equal to N or - 10*M + 2*M*SMLSIZ + 8*M*NLVL + 3*SMLSIZ*NRHS + - (SMLSIZ+1)**2 - if M is less than N, the code will execute correctly. - SMLSIZ is returned by ILAENV and is equal to the maximum - size of the subproblems at the bottom of the computation - tree (usually about 25), and - NLVL = MAX( 0, INT( LOG_2( MIN( M,N )/(SMLSIZ+1) ) ) + 1 ) - - IWORK (workspace) INTEGER array, dimension (LIWORK) - LIWORK >= 3 * MINMN * NLVL + 11 * MINMN, - where MINMN = MIN( M,N ). - - INFO (output) INTEGER - = 0: successful exit - < 0: if INFO = -i, the i-th argument had an illegal value. - > 0: the algorithm for computing the SVD failed to converge;

- - -/* - -- LAPACK routine (version 3.0) -- - Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd., - Courant Institute, Argonne National Lab, and Rice University - October 31, 1999 - - - Purpose - ======= - - CLALSD uses the singular value decomposition of A to solve the least - squares problem of finding X to minimize the Euclidean norm of each - column of A*X-B, where A is N-by-N upper bidiagonal, and X and B - are N-by-NRHS. The solution X overwrites B. - - The singular values of A smaller than RCOND times the largest - singular value are treated as zero in solving the least squares - problem; in this case a minimum norm solution is returned. - The actual singular values are returned in D in ascending order. - - This code makes very mild assumptions about floating point - arithmetic. It will work on machines with a guard digit in - add/subtract, or on those binary machines without guard digits - which subtract like the Cray XMP, Cray YMP, Cray C 90, or Cray 2. - It could conceivably fail on hexadecimal or decimal machines - without guard digits, but we know of none. - - Arguments - ========= - - UPLO (input) CHARACTER*1 - = 'U': D and E define an upper bidiagonal matrix. - = 'L': D and E define a lower bidiagonal matrix. - - SMLSIZ (input) INTEGER - The maximum size of the subproblems at the bottom of the - computation tree. - - N (input) INTEGER - The dimension of the bidiagonal matrix. N >= 0. - - NRHS (input) INTEGER - The number of columns of B. NRHS must be at least 1. - - D (input/output) REAL array, dimension (N) - On entry D contains the main diagonal of the bidiagonal - matrix. On exit, if INFO = 0, D contains its singular values. - - E (input) REAL array, dimension (N-1) - Contains the super-diagonal entries of the bidiagonal matrix. - On exit, E has been destroyed. - - B (input/output) COMPLEX array, dimension (LDB,NRHS) - On input, B contains the right hand sides of the least - squares problem. On output, B contains the solution X. - - LDB (input) INTEGER - The leading dimension of B in the calling subprogram. - LDB must be at least max(1,N). - - RCOND (input) REAL - The singular values of A less than or equal to RCOND times - the largest singular value are treated as zero in solving - the least squares problem. If RCOND is negative, - machine precision is used instead. - For example, if diag(S)*X=B were the least squares problem, - where diag(S) is a diagonal matrix of singular values, the - solution would be X(i) = B(i) / S(i) if S(i) is greater than - RCOND*max(S), and X(i) = 0 if S(i) is less than or equal to - RCOND*max(S). - - RANK (output) INTEGER - The number of singular values of A greater than RCOND times - the largest singular value. - - WORK (workspace) COMPLEX array, dimension at least - (N * NRHS). - - RWORK (workspace) REAL array, dimension at least - (9*N + 2*N*SMLSIZ + 8*N*NLVL + 3*SMLSIZ*NRHS + (SMLSIZ+1)**2), - where - NLVL = MAX( 0, INT( LOG_2( MIN( M,N )/(SMLSIZ+1) ) ) + 1 ) - - IWORK (workspace) INTEGER array, dimension at least - (3*N*NLVL + 11*N). - - INFO (output) INTEGER - = 0: successful exit. - < 0: if INFO = -i, the i-th argument had an illegal value. - > 0: The algorithm failed to compute an singular value while - working on the submatrix lying in rows and columns - INFO/(N+1) through MOD(INFO,N+1). - - Further Details - =============== - - Based on contributions by - Ming Gu and Ren-Cang Li, Computer Science Division, University of - California at Berkeley, USA - Osni Marques, LBNL/NERSC, USA - - ===================================================================== - - - Test the input parameters. -*/ - - /* Parameter adjustments */ - --d__; - --e; - b_dim1 = *ldb; - b_offset = 1 + b_dim1; - b -= b_offset; - --work; - --rwork; - --iwork; - - /* Function Body */ - *info = 0; - - if (*n < 0) { - *info = -3; - } else if (*nrhs < 1) { - *info = -4; - } else if ((*ldb < 1) || (*ldb < *n)) { - *info = -8; - } - if (*info != 0) { - i__1 = -(*info); - xerbla_("CLALSD", &i__1); - return 0; - } - - eps = slamch_("Epsilon"); - -/* Set up the tolerance. */ - - if ((*rcond <= 0.f) || (*rcond >= 1.f)) { - *rcond = eps; - } - - *rank = 0; - -/* Quick return if possible. */ - - if (*n == 0) { - return 0; - } else if (*n == 1) { - if (d__[1] == 0.f) { - claset_("A", &c__1, nrhs, &c_b55, &c_b55, &b[b_offset], ldb); - } else { - *rank = 1; - clascl_("G", &c__0, &c__0, &d__[1], &c_b1011, &c__1, nrhs, &b[ - b_offset], ldb, info); - d__[1] = dabs(d__[1]); - } - return 0; - } - -/* Rotate the matrix if it is lower bidiagonal. */ - - if (*(unsigned char *)uplo == 'L') { - i__1 = *n - 1; - for (i__ = 1; i__ <= i__1; ++i__) { - slartg_(&d__[i__], &e[i__], &cs, &sn, &r__); - d__[i__] = r__; - e[i__] = sn * d__[i__ + 1]; - d__[i__ + 1] = cs * d__[i__ + 1]; - if (*nrhs == 1) { - csrot_(&c__1, &b[i__ + b_dim1], &c__1, &b[i__ + 1 + b_dim1], & - c__1, &cs, &sn); - } else { - rwork[((i__) << (1)) - 1] = cs; - rwork[i__ * 2] = sn; - } -/* L10: */ - } - if (*nrhs > 1) { - i__1 = *nrhs; - for (i__ = 1; i__ <= i__1; ++i__) { - i__2 = *n - 1; - for (j = 1; j <= i__2; ++j) { - cs = rwork[((j) << (1)) - 1]; - sn = rwork[j * 2]; - csrot_(&c__1, &b[j + i__ * b_dim1], &c__1, &b[j + 1 + i__ - * b_dim1], &c__1, &cs, &sn); -/* L20: */ - } -/* L30: */ - } - } - } - -/* Scale. */ - - nm1 = *n - 1; - orgnrm = slanst_("M", n, &d__[1], &e[1]); - if (orgnrm == 0.f) { - claset_("A", n, nrhs, &c_b55, &c_b55, &b[b_offset], ldb); - return 0; - } - - slascl_("G", &c__0, &c__0, &orgnrm, &c_b1011, n, &c__1, &d__[1], n, info); - slascl_("G", &c__0, &c__0, &orgnrm, &c_b1011, &nm1, &c__1, &e[1], &nm1, - info); - -/* - If N is smaller than the minimum divide size SMLSIZ, then solve - the problem with another solver. -*/ - - if (*n <= *smlsiz) { - irwu = 1; - irwvt = irwu + *n * *n; - irwwrk = irwvt + *n * *n; - irwrb = irwwrk; - irwib = irwrb + *n * *nrhs; - irwb = irwib + *n * *nrhs; - slaset_("A", n, n, &c_b320, &c_b1011, &rwork[irwu], n); - slaset_("A", n, n, &c_b320, &c_b1011, &rwork[irwvt], n); - slasdq_("U", &c__0, n, n, n, &c__0, &d__[1], &e[1], &rwork[irwvt], n, - &rwork[irwu], n, &rwork[irwwrk], &c__1, &rwork[irwwrk], info); - if (*info != 0) { - return 0; - } - -/* - In the real version, B is passed to SLASDQ and multiplied - internally by Q'.

- - -/* - -- LAPACK driver routine (version 3.0) -- - Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd., - Courant Institute, Argonne National Lab, and Rice University - October 31, 1999 - - - Purpose - ======= - - SGELSD computes the minimum-norm solution to a real linear least - squares problem: - minimize 2-norm(| b - A*x |) - using the singular value decomposition (SVD) of A. A is an M-by-N - matrix which may be rank-deficient. - - Several right hand side vectors b and solution vectors x can be - handled in a single call; they are stored as the columns of the - M-by-NRHS right hand side matrix B and the N-by-NRHS solution - matrix X. - - The problem is solved in three steps: - (1) Reduce the coefficient matrix A to bidiagonal form with - Householder transformations, reducing the original problem - into a "bidiagonal least squares problem" (BLS) - (2) Solve the BLS using a divide and conquer approach. - (3) Apply back all the Householder tranformations to solve - the original least squares problem. - - The effective rank of A is determined by treating as zero those - singular values which are less than RCOND times the largest singular - value. - - The divide and conquer algorithm makes very mild assumptions about - floating point arithmetic. It will work on machines with a guard - digit in add/subtract, or on those binary machines without guard - digits which subtract like the Cray X-MP, Cray Y-MP, Cray C-90, or - Cray-2. It could conceivably fail on hexadecimal or decimal machines - without guard digits, but we know of none. - - Arguments - ========= - - M (input) INTEGER - The number of rows of A. M >= 0. - - N (input) INTEGER - The number of columns of A. N >= 0. - - NRHS (input) INTEGER - The number of right hand sides, i.e., the number of columns - of the matrices B and X. NRHS >= 0. - - A (input) REAL array, dimension (LDA,N) - On entry, the M-by-N matrix A. - On exit, A has been destroyed. - - LDA (input) INTEGER - The leading dimension of the array A. LDA >= max(1,M). - - B (input/output) REAL array, dimension (LDB,NRHS) - On entry, the M-by-NRHS right hand side matrix B. - On exit, B is overwritten by the N-by-NRHS solution - matrix X. If m >= n and RANK = n, the residual - sum-of-squares for the solution in the i-th column is given - by the sum of squares of elements n+1:m in that column. - - LDB (input) INTEGER - The leading dimension of the array B. LDB >= max(1,max(M,N)). - - S (output) REAL array, dimension (min(M,N)) - The singular values of A in decreasing order. - The condition number of A in the 2-norm = S(1)/S(min(m,n)). - - RCOND (input) REAL - RCOND is used to determine the effective rank of A. - Singular values S(i) <= RCOND*S(1) are treated as zero. - If RCOND < 0, machine precision is used instead. - - RANK (output) INTEGER - The effective rank of A, i.e., the number of singular values - which are greater than RCOND*S(1). - - WORK (workspace/output) REAL array, dimension (LWORK) - On exit, if INFO = 0, WORK(1) returns the optimal LWORK. - - LWORK (input) INTEGER - The dimension of the array WORK. LWORK must be at least 1. - The exact minimum amount of workspace needed depends on M, - N and NRHS. As long as LWORK is at least - 12*N + 2*N*SMLSIZ + 8*N*NLVL + N*NRHS + (SMLSIZ+1)**2, - if M is greater than or equal to N or - 12*M + 2*M*SMLSIZ + 8*M*NLVL + M*NRHS + (SMLSIZ+1)**2, - if M is less than N, the code will execute correctly. - SMLSIZ is returned by ILAENV and is equal to the maximum - size of the subproblems at the bottom of the computation - tree (usually about 25), and - NLVL = MAX( 0, INT( LOG_2( MIN( M,N )/(SMLSIZ+1) ) ) + 1 ) - For good performance, LWORK should generally be larger. - - If LWORK = -1, then a workspace query is assumed; the routine - only calculates the optimal size of the WORK array, returns - this value as the first entry of the WORK array, and no error - message related to LWORK is issued by XERBLA. - - - IWORK (workspace) INTEGER array, dimension (LIWORK) - LIWORK >= 3 * MINMN * NLVL + 11 * MINMN, - where MINMN = MIN( M,N ). - - INFO (output) INTEGER - = 0: successful exit - < 0: if INFO = -i, the i-th argument had an illegal value. - > 0: the algorithm for computing the SVD failed to converge; - if INFO = i, i off-diagonal elements of an intermediate - bidiagonal form did not converge to zero. - - Further Details - =============== - - Based on contributions by - Ming Gu and Ren-Cang Li, Computer Science Division, University of - California at Berkeley, USA - Osni Marques, LBNL/NERSC, USA - - ===================================================================== - - - Test the input arguments. -*/ - - /* Parameter adjustments */ - a_dim1 = *lda;
