Is x of a sparse matrix type?

Parameters:
x

object to check for being a sparse matrix

Returns:
bool

True if x is a sparse matrix, False otherwise

Examples

>>> import numpy as np
>>> from scipy.sparse import csr_array, csr_matrix, isspmatrix
>>> isspmatrix(csr_matrix([[5]]))
True
>>> isspmatrix(csr_array([[5]]))
False
>>> isspmatrix(np.array([[5]]))
False
>>> isspmatrix(5)
False
