# scipy.linalg.blas

## 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.
