scipy.sparse.isspmatrix_dia(x)

Is x of dia_matrix type?

Parameters

x

object to check for being a dia matrix

Returns

bool

True if x is a dia matrix, False otherwise

Examples

>>> from scipy.sparse import dia_matrix, isspmatrix_dia
>>> isspmatrix_dia(dia_matrix([[5]]))
True

>>> from scipy.sparse import dia_matrix, csr_matrix, isspmatrix_dia
>>> isspmatrix_dia(csr_matrix([[5]]))
False
