* BLD: enabled negation of library choices in NPY_*_ORDER (#17219)Nick R. Papior2020-09-171-0/+12
| | | | | | | | | | | | | | | | | | | | | | | BLD: enabled negation of library choices in NPY_*_ORDER When users build for a particular order it may be beneficial to disallow certain libraries. In particular a user may not care about which accelerated BLAS library is used, so long as the NetLIB or ATLAS library isn't used. This is now possible with: NPY_BLAS_ORDER='^blas,atlas' or NPY_BLAS_ORDER='!blas,atlas' Since we may envision more BLAS/LAPACK libraries to the pool, this will provide greater flexibility as they enter. A new (local) method is added in system_info.py which removes duplicate code and allows for easier usage across libraries.
* ENH: Allow genfromtxt to unpack structured arrays (#16650)Andrew Eckart2020-09-111-0/+16
| | | | | | | | | | | | | * ENH: Allow genfromtxt to unpack structured arrays genfromtxt failed to transpose output when unpack=True and `dtype` was structured (or None). This patch resolves the issue by returning a list of arrays, as in `loadtxt`.

| * ENH: Implement concatenate dtype and casting keyword argumentsSebastian Berg2020-09-022-0/+14
| | | | | | | | | | | | | | Unfortunately, the casting was not consistent and sometimes used force casting (axis=None) while normally same kind casting was used. This thus deprecates the `force_casting` corner case, so that casting has to be provided in the future.

| | | | | | | | | | | | | | | | We no longer need to use the compatibility function after dropping support for Python 2.7. In some cases unicode was the correct string type rather than the bytes of the compatibility version and bugs in the array `__complex__` and array `__array_interface__` methods have been fixed by changing that.

| |/ |/| | | | | | | | | | | | | | | As explained in NEP 32, the financial functions are to be removed from version 1.20. They are now replaced with module level `__getattr__` to give a useful error message for those surprised by the `AttributeError`. This only works for Python 3.7+, but it is expected that by the 1.20 release Python 3.6 will not be supported.
* | BUG: Raise correct errors in boolean indexing fast path (gh-17010)Aaron Meurer2020-08-061-0/+24
| | | | | | | | | | | | | | | | | | | | Previously the logic assumed that an index was valid if the size was the same as the indexed array, rather than the shape. This resulted in an index being incorrectly allowed if the index was all False, like np.empty((3, 3))[np.full((1, 9), False)], or incorrectly giving a ValueError about broadcasting if the index was not all False (like np.empty((3, 3))[np.full((1, 9), True)]). Now these examples both give IndexError with the usual error message. Fixes #16997.

* | DEP: Deprecate ufunc.outer with matrix inputsSebastian Berg2020-07-161-0/+6
| | | | | | | | | | | | | | | | | | | | Previously we converted matrices to arrays for the user, since `np.outer` does not make sense for matrix. This deprecates that usage (which in almost all cases will result in an error). The main reason for this deprecation is to remove all direct references of matrix from the NumPy codebase, so that it is easier to move it out of NumPy eventually.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kwarg option norm=inverse leads to scaling of the transforms inverse (opposite) to that of the default option norm=None; i.e. the forward transform is normalized with 1/n whereas the backward one with 1.
