Low-level LAPACK functions (scipy.linalg.lapack)

This module contains low-level functions from the LAPACK library.

The *gegv family of routines have been removed from LAPACK 3.6.0 and have been deprecated in SciPy 0.17.0. They will be removed in a future release.

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_lapack_funcs(names[, arrays, dtype])

Return available LAPACK function objects from names.
