BLAS Functions for Cython
=========================

Usable from Cython via::

    cimport scipy.linalg.cython_blas

These wrappers do not check for alignment of arrays.
Alignment should be checked before these wrappers are used.

If using ``cdotu``, ``cdotc``, ``zdotu``, ``zdotc``, ``sladiv``, or ``dladiv``,
the ``CYTHON_CCOMPLEX`` define must be set to 0 during compilation. For
example, in a ``meson.build`` file when using Meson::

    py.extension_module('ext_module'
        'ext_module.pyx',
        c_args: ['-DCYTHON_CCOMPLEX=0'],
        ...
    )

# Within SciPy, these wrappers can be used via relative or absolute cimport.
# Examples:
# from ..linalg cimport cython_blas
# from scipy.linalg cimport cython_blas
# cimport scipy.linalg.cython_blas as cython_blas
# cimport ..linalg.cython_blas as cython_blas

# Within SciPy, if BLAS functions are needed in C/C++/Fortran,
# these wrappers should not be used.
# The original libraries should be linked directly.
