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.
