# scipy.sparse.rand

`scipy.sparse.``rand`(m, n, density=0.01, format='coo', dtype=None, random_state=None)

  Generate a sparse matrix of the given shape and density with uniformly distributed values.

  Parameters: | m, n : int shape of the matrix density : real, optional density of the generated matrix: density equal to one means a full matrix, density of 0 means a matrix with no non-zero items. format : str, optional sparse matrix format. dtype : dtype, optional type of the returned matrix values. random_state : {numpy.random.RandomState, int}, optional Random number generator or random seed. If not given, the singleton numpy.random will be used.

  Notes

  Only float types are supported for now.
