Evolution2d

Function: evolution2d ([<F>, <G>], [<u>, <v>], [<u0>, <y0>], <n>, ..., options, ...); Shows, in a two-dimensional plot, the first <n+1> points in the sequence of points defined by the two-dimensional discrete dynamical system with recurrence relations u(n+1) = F(u(n), v(n)) v(n+1) = G(u(n), v(n))

f: 0.6*x*(1+2*x)+0.8*y*(x-1)-y^2-0.9;
 g: 0.1*x*(1-6*x+4*y)+0.1*y*(1+9*y)-0.4;
 evolution2d([f,g], [x,y], [-0.5,0], 50000, [style,dots]);

With initial values <u0> and <v0>. <F> and <G> must be two expressions that depend only on two variables, <u> and <v>, which must be named explicitely in a list.
