# scipy.linalg.blas.find_best_blas_type

`scipy.linalg.blas.``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 : sequence of ndarrays, optional Arrays can be given to determine optimal 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.
