# scipy.sparse.isspmatrix_dok

scipy.sparse.isspmatrix_dok(x)

  Is x of dok_matrix type?

  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_matrix, isspmatrix_dok
      >>> isspmatrix_dok(dok_matrix([[5]]))
      True

      >>> from scipy.sparse import dok_matrix, csr_matrix, isspmatrix_dok
      >>> isspmatrix_dok(csr_matrix([[5]]))
      False
