scipy.sparse.linalg.LaplacianNd.
rmatvec#
- LaplacianNd.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.
