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.
