scipy.sparse.linalg.LinearOperator.
matvec#
- LinearOperator.matvec(x)[source]#
- Matrix-vector multiplication. - 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.
