Hello all,
unfortunately I am getting a syntax error in Simulink in two Fcn blocks:
1) c1*(1-exp(-c2*u))-c3*u
2) cw*A*rho/2*u^2
I really can't find the problem in this so a little help is appreciated.
Many thanks in advace!

Make sure the variables “c1”, “c2”, “u”, “c3”, “cw”, “A” and “rho” are defined in the MATLAB workspace or in one of the callbacks of the Simulink Model. The syntax for both equations is correct.
Furthermore, the denominator of equation 2 has a squaring operation, therefore care should be taken if “u” is a vector.
