scipy.linalg.find_best_blas_type

scipy.linalg.find_best_blas_type(arrays=(), dtype=None)

Find best-matching BLAS/LAPACK type.

Arrays are used to determine the optimal prefix of BLAS routines.

Parameters :

arrays : sequency of ndarrays, optional

Arrays can be given to determine optiomal prefix of BLAS routines. If not given, double-precision routines will be used, otherwise the most generic type in arrays will be used.

dtype : str or dtype, optional

Data-type specifier. Not used if arrays is non-empty.

Returns :

prefix : str

BLAS/LAPACK prefix character.

dtype : dtype

Inferred Numpy data type.

prefer_fortran : bool

Whether to prefer Fortran order routines over C order.
