# rmatmat

LaplacianNd.rmatmat(X)

  Adjoint matrix-matrix multiplication.

  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.
