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

source: build-install/usr/lib/python3.14/site-packages/scipy/sparse/linalg/_interface.py:495

Signature

def rmatmat(self, X)

Summary

Adjoint matrix-matrix multiplication.

Extended Summary

Performs the operation A^H @ X where A is an M x N linear operator (or batch of linear operators) and X is a dense M x K matrix (or batch of dense matrices). The default implementation defers to the adjoint.

Parameters

X : {matrix, ndarray}: An array with shape (..., M, K) representing the dense matrix (or batch of dense matrices).

Returns

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

Notes

This method wraps any user-specified rmatmat routine or overridden _rmatmat method to ensure that Y has the correct type.
