Hi, I tried to use solve in the following fashion:

if true
  % code
end
syms a x C
Csolve = solve(C+pi*cos(a)+pi*i*sin(a)-C*exp^(i*a)*cos(a)-C*exp^(i*a)*i*sin(a)==0)

However, it returns "Not enough parameters"

Is there a particular missing part here?

Thanks!

Csolve = solve(C+pi*cos(a)+pi*1i*sin(a)-C*exp(1i*a)*cos(a)-C*exp(1i*a)*1i*sin(a)==0,C)

Best wishes

Torsten.

"exp^" should produce an error message, or MATLAB interprets "exp" as a variable name (though undefined in your code from above).

so it should only be exp indeed! Thanks, forgot it there.
