Parameters ---------- x object to check for being a sparse array or sparse matrix Returns ------- bool True if `x` is a sparse array or a sparse matrix, False otherwise Notes ----- Use `isinstance(x, sp.sparse.sparray)` to check between an array or matrix. Use `a.format` to check the sparse format, e.g. `a.format == 'csr'`. Examples -------- >>> import numpy as np >>> from scipy.sparse import csr_array, csr_matrix, issparse >>> issparse(csr_matrix([[5]])) True >>> issparse(csr_array([[5]])) True >>> issparse(np.array([[5]])) False >>> issparse(5) False ) isinstancer)xs r rr s> a # ##r N)abcr__all__rrr r r rsd  #        $$$$$r
