function

scipy._lib._sparse:issparse

source: /scipy/_lib/_sparse.py :10

Signature

def   issparse ( x )

Summary

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]]))
issparse(csr_array([[5]]))
issparse(np.array([[5]]))
issparse(5)
