# scipy.sparse.isspmatrix

scipy.sparse.isspmatrix(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

  Examples

      >>> import numpy as np
      >>> from scipy.sparse import csr_array, csr_matrix, isspmatrix
      >>> isspmatrix(csr_matrix([[5]]))
      True
      >>> isspmatrix(csr_array([[5]]))
      False
      >>> isspmatrix(np.array([[5]]))
      False
      >>> isspmatrix(5)
      False
