rmatmat#
- LbfgsInvHessProduct.rmatmat(X)[source]#
- Adjoint matrix-matrix multiplication. - Performs the operation y = A^H @ x where A is an MxN linear operator and x is a column vector or 1-d array, or 2-d array. The default implementation defers to the adjoint. - Parameters:
- X{matrix, ndarray}
- A matrix or 2D array. 
 
- Returns:
- Y{matrix, ndarray}
- A matrix or 2D array depending on the type of the input. 
 
 - Notes - This rmatmat wraps the user-specified rmatmat routine.
