Low-level BLAS functions¶
This module contains low-level functions from the BLAS library.
New in version 0.12.0.
Warning
These functions do little to no error checking. It is possible to cause crashes by mis-using them, so prefer using the higher-level routines in scipy.linalg.
Finding functions¶
| get_blas_funcs(names[, arrays, dtype]) | Return available BLAS function objects from names. |
| find_best_blas_type([arrays, dtype]) | Find best-matching BLAS/LAPACK type. |
