I am trying to run a simulink block diagram simulation.
I have the following function in a func block: (( Y* (abs(u(nb+1))<Tfault) ) +(( Yf * (abs(u(nb+1))>=Tfault)) & (abs(u(nb+1)) <(Tfault+Tclear) )) + (Ypf * (abs(u(nb+1)) >= (Tfault+Tclear) ))) \ u(1:nb)
Y,Yf,Ypf are matrices
no matter what I do I continue to get a syntax error and I simply cannot see what the problem is. Can someone please tell me what is wrong with this function.

  1. Provide values for every variable in the formula, including nb, Tfault, Tclear
  2. Provide an instance value of u
  3. Run the formula chunck by chunk, like Y* (abs(u(nb+1))<Tfault) and then Yf * (abs(u(nb+1))>=Tfault), and then the next
  4. You will find the problem, such as missing a parentheses
