-    Compares two sparse matrices in the same matter like numpy.allclose()
-    Parameters
-    ----------
-    A : scipy.sparse matrix
-        first matrix to compare
-    B : scipy.sparse matrix
-        second matrix to compare
-    rtol : float
-        relative tolerance
-    atol : float
-        absolute tolerance
-    
-    Returns
-    -------
-    True, if given matrices are equal in bounds of rtol and atol
-    False, otherwise
-    
-    Notes
-    -----
-    If the following equation is element-wise True, then allclose returns
-    True.
-
-     absolute(`a` - `b`) <= (`atol` + `rtol` * absolute(`b`))
-
-    The above equation is not symmetric in `a` and `b`, so that
-    `allclose(a, b)` might be different from `allclose(b, a)` in
-    some rare cases.
