Question: Error number of equations, 1, does not match number of variables, 2. BUT IT IS JUST ONE!!!

  Dear all, I am using fsolve to solve a complex equation. When I solve it, I get the following error:

Error number of equations, 1, does not match number of variables, 2.

But the variables are just one (named u1) I think it is a problem with assume but I am getting cracy to understand the problem.You can find in attachment the short maple file. I try to solve equation e4 for variable u1.

thanks
Alberto
