function

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

source: /scipy/sparse/linalg/_interface.py :231

Signature

def matvec ( self , x )

Summary

Matrix-vector multiplication.

Extended Summary

Performs the operation y=A@x where A is an MxN linear operator and x is a column vector or 1-d array.

Parameters

x : {matrix, ndarray}: An array with shape (N,) or (N,1).

Returns

y : {matrix, ndarray}: A matrix or ndarray with shape (M,) or (M,1) depending on the type and shape of the x argument.

Notes

This matvec wraps the user-specified matvec routine or overridden _matvec method to ensure that y has the correct shape and type.
