Hello, I have a n dimensional nonlinear vectorfield (algebraic equation): f(x,t)=0 where x is a vector and t the time. For the time t=t0 there are two solutions: First solution: f(x1,t0)=0 with the initial point x01 Second Solution: f(x2,t0)=0 with the initial point x02 My Problem: I have x01, so I can get the solution vector x1 with a numerical solver. But the numerical solver only finds x1. But I need also the second solution x2! Question: How can I get the second vector x2? Or a good approximation of x2? Thanks!
