function A = cs_frand (n,nel,s) %#ok %CS_FRAND generate a random finite-element matrix % A = cs_frand (n,nel,s) creates an n-by-n sparse matrix consisting of nel % finite elements, each of which are of size s-by-s with random symmetric % nonzero pattern, plus the identity matrix. % % Example % A = cs_frand (100, 100, 3) ; % See also cs_demo. % Copyright 2006, Timothy A.
