scipy.sparse.linalg.inv

scipy.sparse.linalg.inv(A)[source]

Compute the inverse of a sparse matrix

New in version 0.12.0.

Parameters :

A : (M,M) ndarray or sparse matrix

square matrix to be inverted

Returns :

Ainv : (M,M) ndarray or sparse matrix

inverse of A

Notes

This computes the sparse inverse of A. If the inverse of A is expected to be non-sparse, it will likely be faster to convert A to dense and use scipy.linalg.inv.
