* BUG: linalg: lstsq should always return real residuals (#937)Pauli Virtanen2010-10-101-3/+80
|
* ENH: Add slogdet to the linalg module. The patch is from njs withCharles Harris2010-05-051-0/+19
| | | | slogdet substituted for sign_log_det. Closes ticket #1402.
* ENH - added matrix_rank function to linalgMatthew Brett2009-12-221-1/+21
|
* linalg: support '0-norm' (scipy ticket #1037)Pauli Virtanen2009-11-061-0/+2
|
* Fix eigenvalue tests, the eigenvalues needed sorting.Charles Harris2009-03-271-8/+8
| | | | Fix test_nanmin_alnan_on_axis, use assert_array_equal.
* BUG: fix #786, bad exception for wrong order for linalg.norm.David Cournapeau2009-03-021-6/+0
|
* Fix norm tests for single prec.David Cournapeau2009-03-021-11/+27
|
* Abstract away dtype for norm test.David Cournapeau2009-03-021-8/+14
|
* rename check_empty method to test_, so that is is picked up by nose.David Cournapeau2009-03-021-1/+1
|
* TEST: add tests for norm from #763.David Cournapeau2009-03-021-1/+41

* Added tests for eigenvalue/vector functions for Hermitian matrices..Alan McIntyre2008-07-141-0/+55

* Clean up test output such that a completely-passing test suite has no ↵Robert Kern2008-07-031-3/+1
| | | | extraneous output.
* Restore old test framework classes.Alan McIntyre2008-06-211-1/+1
| | | | | | | | | | | Added numpy.testing.run_module_suite to simplify "if __name__ == '__main__'" boilerplate code in test modules. Removed numpy/testing/pkgtester.py since it just consisted of an import statement after porting SciPy r4424. Allow numpy.*.test() to accept the old keyword arguments (but issue a deprecation warning when old arguments are seen). numpy.*.test() returns a test result object as before. Fixed typo in distutils doc.
* Switched to use nose to run tests. Added test and bench functions to all ↵Alan McIntyre2008-06-171-25/+27

* Keep singular values and eigenvalues as 1D arrays until the matrix indexingCharles Harris2008-04-291-4/+0
| | | | | controversy is settled. This will also keep code that uses diag(ev), from breaking.
* Fix test of lstsqr to work with matrix tests.Charles Harris2008-04-271-1/+1
| | | | Fix lstsq
* Add tests for matrix return types.Charles Harris2008-04-271-6/+38
| | | | | Fix cond computations for matrices. lstsq is currently broken for matrices, will fix shortly.
* Make functions in linalg.py accept nestes lists.Charles Harris2008-04-271-8/+14
| | | | | Use wrap to keep matrix environment intact. Base patch from nmb.
* Added function for computing condition number, with tests and docs; closes #622.aarchiba2008-04-081-1/+16
|
* Test that matrix_power behaves correctly for boolean matrices.aarchiba2008-04-071-0/+4
|
* Factor out matrix_multiply from defmatrix. Based on a patch byStefan van der Walt2008-04-061-8/+62
| | | | Anne Archibald.
* Apply patch to fix ticket #557 (pinv causing error with empty arrays)Travis Oliphant2007-09-211-1/+10
|
* Fix failing linalg.tests.test_det on 32-bit machines for csingle.cookedm2006-07-141-1/+5
| | | | | | This compares det() with the product of the eigenvalues, which were being calculated as csingles. Changing that to cdouble makes this work. I have no clue why this fails for 32-bit linux, but not 64-bit.
* numpy.linalg: fix bug where complex arrays weren't being returned.cookedm2006-07-141-8/+14
| | | | Also improved test cases.
* Add test cases for linalgcookedm2006-07-141-0/+80
