package sklearn

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

Notes ----- issparse and isspmatrix are aliases for the same function.

Examples -------- >>> from scipy.sparse import csr_matrix, isspmatrix >>> isspmatrix(csr_matrix([5])) True

>>> from scipy.sparse import isspmatrix >>> isspmatrix(5) False

Is x of csr_matrix type?

Parameters ---------- x object to check for being a csr matrix

Returns ------- bool True if x is a csr matrix, False otherwise

Examples -------- >>> from scipy.sparse import csr_matrix, isspmatrix_csr >>> isspmatrix_csr(csr_matrix([5])) True

>>> from scipy.sparse import csc_matrix, csr_matrix, isspmatrix_csc >>> isspmatrix_csr(csc_matrix([5])) False
