scipy.sparse.linalg.LinearOperator.
rmatvec#
- LinearOperator.rmatvec(x)[source]#
- Adjoint matrix-vector 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. - Parameters:
- x{matrix, ndarray}
- An array with shape (M,) or (M,1). 
 
- Returns:
- y{matrix, ndarray}
- A matrix or ndarray with shape (N,) or (N,1) depending on the type and shape of the x argument. 
 
 - Notes - This rmatvec wraps the user-specified rmatvec routine or overridden _rmatvec method to ensure that y has the correct shape and type.
