Hi, I have an output from a Solve that returns a solution as a list of rules. Each branch of the solution is a two-parametric function e.g. {{ x -> Something(a,b), y->Something(a,b)},... I want to plot a specific branch of the solution with Plot3D as a function of {a,b}. I tried to assign a solution branch to a function sol11[a,b] sol11[a_,b_]=%[[1,1]] and to plot sol11 but it doesn't work. How can I access a parametric solution as returned from Solve as a function of it's parameters? Thanks, Ted
