scipy.sparse.
issparse#
- scipy.sparse.issparse(x)[source]#
- Is x of a sparse array or sparse matrix type? - Parameters:
- x
- object to check for being a sparse array or sparse matrix 
 
- Returns:
- bool
- True if x is a sparse array or a sparse matrix, False otherwise 
 
 - Notes - Use isinstance(x, sp.sparse.sparray) to check between an array or matrix. Use a.format to check the sparse format, e.g. a.format == ‘csr’. - Examples - >>> import numpy as np >>> from scipy.sparse import csr_array, csr_matrix, issparse >>> issparse(csr_matrix([[5]])) True >>> issparse(csr_array([[5]])) True >>> issparse(np.array([[5]])) False >>> issparse(5) False
