| | | | | | | | | | | | | | | | Deprecate the fastCopyAndTranspose function from the Python API, and the underlying PyArray_CopyAndTranspose function from the C-API. Also removes an internal, private function _fastCopyAndTranspose which was the original Python wrapper around the C-function.

* PERF: Reduce overhead of np.linalg.norm for small arrays (#21394)Pieter Eendebak2022-05-031-2/+4
| | | | Reduce the overhead of np.linalg.norm by replacing dot(x,x) with x.dot(x). This is OK, since `x` is converted to a base-class array here.
* BUG: Consistent promotion for norm for all values of ord (#17709)Toshiki Kataoka2022-04-071-2/+3
| | | | | | | | | Previously, numpy.linalg.norm would return values with the same floating-point type as input arrays for most values of the ``ord`` parameter, but not all. This PR fixes this so that the output dtype matches the input for all (valid) values of ``ord``.

| | | `u @ np.diag(s) @ vh` can only reproduce the original matrix when `full_matrices` is `False`, otherwise dimension does not match.
* DOC: clarify the return value of linalg.choleskyStephan Hoyer2022-02-171-2/+2
| | | | | It is in fact always lower-triangular. The errorenous note might date to when function was forked from SciPy?
* BUG: Fix tensorsolve for 0-sized inputIvan Yashchuk2021-11-291-1/+7
| | | | | | | | `array.reshape(-1, size)` doesn't work with 0 in the dimensions. The fix is to use explicit shape instead of `-1`. For "non-square" tensors the `ValueError` would come from the reshape call, while previously `LinAlgError` appeared from the solve call. To have the same error type I added a check for squareness before the reshape.

| | | | | | | | | | | | | | It turns out that lstsq also minimizes the 2-norm of x when a is rank-deficient. I found that by searching the documentation for the LAPACK library, which is the current implementation of lstsq (as of Dec 2020). Ref: https://www.netlib.org/lapack/lug/node27.html
* | Fix some inconsistencies in the docstring of matrix_rankAaron Meurer2021-06-111-22/+22
|/ | | | | | | | | - Rename the argument from M to A, since M already refers to the number of rows in the docstring. - Fix the documentation for the formula for the default value of tol. It only uses the maximum of the number of rows and columns, not the max of all dimensions. The code here was correct; only the documentation was wrong.
