Hello,
I have a complex symbolic fraction.
syms U_1 R C omega positive
U_2 = -(U_1*sym(1i))/(C^2*R^2*omega^sym(2)*sym(1i) + 3*C*R*omega - sym(1i))
How can i get rid of the imaginary unit as common factor in the numerator and the denominator of this fraction.
simplifyFraction(U_2)
does not work.
Kind regards
Michael

[N, D] = numden(U_2)
U_2a = (N*1i)/(D*1i)

Yes, of course there are other options. For example you could use feval(symengine) to pass commands directly into the symbolic engine using MuPad language constructs.
But you are not going to be able to just call simplify() or rewrite()
