|\ | | | | DOC: fixed correlate docstring.
| * DOC: replaced typeset formulas by pure ASCII equivalents.Bernhard Spinnler2013-10-151-13/+12
| | | | | | | | | | Replaced typeset formulas by pure ASCII equivalents. Should now be easier to read in source files.
| * DOC: fixed correlate docstring.Bernhard Spinnler2013-10-131-7/+34
| | | | | | | | | | Replaced correlation formula with corrected version that matches the numpy implementation. Added comment on possible further different definitions of correlation. Added examples.

* | | BUG: cov/corrcoef complex input and empty arraysJoseph Martinot-Lagarde2013-10-162-27/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This preserves the complex (and higher precision float or object) type of the input array, so that the complex covariance and correlation coefficients can be calculated. It also fixes the the behaviour of empty arrays. These will now either result in a 0x0 result, or a NxN result filled with NaNs. A warning is now issued when ddof is too large and the factor set to 0 so that in this case the result is always NaN or infinity/negative infinity and never a negative number. Closes gh-597 and gh-2680 Closes gh-3882 (original pull request)

* | | Fix example plot of Laplace distributionNiklas Koep2013-10-151-2/+2
| | | | | | | | | In the PDF used for the example plot of the Laplace distribution only the location parameter loc instead of the absolute difference between random variable and loc was divided by the scale parameter. For the example at hand this makes no difference as loc is 0 and lambda is 1. For different values, however, the plot makes no sense.
* | | BUG: Check that npyiter is not too largeSebastian Berg2013-10-152-1/+15
| | | | | | | | | | | | | | | Since NpyIter keeps track of the total size, this cannot be larger then npy_intp, so that an overflow check is necessary.

| * | ENH: speed up intp multiply overflow checkJulian Taylor2013-09-283-11/+26
| | | | | | | | | | | | | | | | | | | | | Avoid expensive division by checking against half size of the result first. Speeds up PyArray_NewFromDescr by a factor of two according to perf. Could still be further improved by making use of cpu overflow flags, e.g. via clangs __builtin_mul_with_overflow or using gccs __int128 type.

| * | MAINT: accept NULL in NpyIter_Deallocate and remove redundant NULL checksJulian Taylor2013-10-0310-103/+45
| | | | | | | | | | | | | | | | | | | | | | | | Deallocation should just do nothing if provided a NULL pointer nditer deletion broke this convention. Removed many redundant NULL checks for various deallocation functions used in numpy, they all end up in standard C free or PyMem_Free which are both NULL safe.
