function

`scipy.sparse.linalg._interface:LinearOperator.matmat`

source: /scipy/sparse/linalg/_interface.py :337

Signature

def matmat ( self , X )

Summary

Matrix-matrix multiplication.

Extended Summary

Performs the operation y=A@X where A is an MxN linear operator and X dense N*K matrix or ndarray.

Parameters

X : {matrix, ndarray}: An array with shape (N,K).

Returns

Y : {matrix, ndarray}: A matrix or ndarray with shape (M,K) depending on the type of the X argument.

Notes

This matmat wraps any user-specified matmat routine or overridden _matmat method to ensure that y has the correct type.
