public class cell
extends ExternalFunction

An external function for creating matrices that consist of zeros * everywhere except in the diagonal. The diagonal consists of ones. * (e.g.: eye(3) will return a 3-by-3 matrix [1,0,0;0,1,0;0,0,1], * eye(4,3) will return a 4-by-3 matrix with diagonal set to 1
