# scipy.sparse.issparse

scipy.sparse.issparse(x)

  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
