scipy.sparse.linalg.LaplacianNd.
matvec#
- LaplacianNd.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.
