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_array, dia_matrix, coo_matrix, isspmatrix_dia
>>> isspmatrix_dia(dia_matrix([[5]]))
True
>>> isspmatrix_dia(dia_array([[5]]))
False
>>> isspmatrix_dia(coo_matrix([[5]]))
False
