Hi, I am new to Mathematica and need to solve urgently a system of two nonlinear difference equations that takes the following form: x(n) = f[z(n)], z(n+1) = g[z(n), z(n)], where where n is time f[] and g[] are nonlinear functional forms. An obvious solution is to substitute out for x(n) from the first equation in the second and solve a single equation in m(n), using RSOLVE. However, I would prefer to learn how to solve the two equations simultaneously. If anybody can direct me to some existing code, I would be most grateful. R
