* BUG: distance arg of np.gradient must be scalar, fix docstringAllan Haldane2016-05-111-5/+7
| | | | | | | Fixups to docstring, and disallow non-scalars as the distance args to np.gradient. Fixes #7548, fixes #6847

* DOC: Updated documentation to reflect changes to bin estimators.Joseph Fox-Rabinovitz2016-03-161-26/+40
| | | | | Described ad nauseum the relationship between `range` parameter and bin estimation. Updated formulas for estimators now that they are returning bin widths.
* BUG: Incorrect handling of range in `histogram` with automatic bins.Joseph Fox-Rabinovitz2016-03-161-65/+70
| | | | | Fixes #7411. Tests and documentation updated. Fixes other small issues with range and bin count computations.
* BUG: Fix string copying for np.placegfyoung2016-03-151-1/+2
| | | | | | | | | | | | | | | | Fixes bug in string copying in np.place in which replacements strings that were smaller than their replaced elements would only partially replace the element instead of the entire element. Closes gh-6974. Addendum: this commit also appears to have fixed issue with overflow for very large input arrays. Closes gh-7207.

|\ | | | | Tweak corrcoef
| * MAINT/BUG: Clip real and imag parts of corrcoef return to [-1, 1].Charles Harris2016-03-131-5/+19
| | | | | | | | | | | | | | | | | | | | The non-nan elements of the result of corrcoef should satisfy the inequality abs(x) <= 1 and the non-nan elements of the diagonal should be exactly one. We can't guarantee those results due to roundoff, but clipping the real and imaginary parts to the interval [-1, 1] improves things to a small degree. Closes #7392.

| | | | | | | | | | The input arrays are documented to have ndim <=2, so check for that and raise a ValueError on failure.

* | TST: Fixed shuffle axis in tests.Joseph Fox-Rabinovitz2016-02-221-1/+1
| | | | | | | | | | | | | | | | Since shuffle only works along the first dimension, it must be done before reshape to get reasonable looking data. Did not affect the current tests. I noticed while working on some scipy code. Also, made a couple of doc changes to np.random.shuffle.

* DEP: Stricter arg checking for array orderinggfyoung2015-12-181-4/+6
| | | | | | | | | | | | | The bug traces to the PyArray_OrderConverter method in conversion_utils.c, where no errors are thrown if the ORDER parameter passed in is not of the string data-type or has a string value of length greater than one. This commit causes a DeprecationWarning to be raised, which will later be turned into a TypeError or another type of error in a future release. Closes gh-6598.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We calculate sqrt on the small vector rather than on that huge product matrix and we combine the "outer" product with element-wise devision. So even though we have a slower loop over the rows now ... this code snippet runs about 3 times faster than before. However the speed improvement of the whole function is not really significant because cov() takes 80-99% of the time (dependent on blas/lapack implementation and number of CPU cores). More important is that we will safe 1/3 memory. For example corrcoef() for a [23k, m] matrix needs 8GB now instead of 12GB.
