So,when you use from: real(besseli(1,z)) or,in total: real(my_final_equation) in fact you separate only real and imaginary parts in out of argument.but,my complex unknown exist within bessel arguments,aslo. So,when I introduce "syms bet" and write the code and finally use from: exp2(i) = fsolve(@(bet)eval(exp1(i)),my_guess); in fact,"bet" unknown is a parameter (inexp1(i)) equation),and MATLAB with real and imag command,can not separate real and imaginary parts of "bet". it is clear my explanations? thank you very much for your attention... ghasem
