isspmatrix_dok#

scipy.sparse.isspmatrix_dok(x)[source]#

Is x of dok_array type?

Warning

SciPy sparse is shifting from a sparse matrix interface to a sparse array interface. In the next few releases we expect to deprecate the sparse matrix interface. For documentation of the matrix interface, see the spmatrix interface docs. For guidance on converting existing code to sparse arrays, see Migration from spmatrix to sparray.

Parameters:
x

object to check for being a dok matrix

Returns:
bool

True if x is a dok matrix, False otherwise

Examples

>>> from scipy.sparse import dok_array, dok_matrix, coo_matrix, isspmatrix_dok
>>> isspmatrix_dok(dok_matrix([[5]]))
True
>>> isspmatrix_dok(dok_array([[5]]))
False
>>> isspmatrix_dok(coo_matrix([[5]]))
False
