Low-level BLAS functions (scipy.linalg.blas)¶
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. |
