scipy.sparse.linalg.aslinearoperator

scipy.sparse.linalg.aslinearoperator(A)

Return A as a LinearOperator.

‘A’ may be any of the following types:

• ndarray
• matrix
• sparse matrix (e.g. csr_matrix, lil_matrix, etc.)
• LinearOperator
• An object with .shape and .matvec attributes

See the LinearOperator documentation for additional information.

Examples

>>> from scipy.sparse.linalg import aslinearoperator
>>> M = np.array([[1,2,3],[4,5,6]], dtype=np.int32)
>>> aslinearoperator(M)
<2x3 MatrixLinearOperator with dtype=int32>
