scipy.sparse.linalg.aslinearoperator¶
-
scipy.sparse.linalg.
aslinearoperator
(A)[source]¶ 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.
Notes
If ‘A’ has no .dtype attribute, the data type is determined by calling
LinearOperator.matvec
- set the .dtype attribute to prevent this call upon the linear operator creation.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>
