Hello all,
I have problems getting FindRoot to evaluate the equations it evaluates,
despite using Evaluate on the equations. I have a rather complex
function f[x,y] that works correctly with individual values x and y.
Evaluating the following expression does not work however.
FindRoot[Evaluate[f[x,y]==0],{{x,1},{y,1}}]
When evaluating, I get similar errors as when I evaluate f without
inserting values for x and y. I can also do a Plot3D on f without using
Evaluate.
Does anybody have an idea what the problem is?
Jonas
