Function: evolution2d (
], <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))
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.
