Hello Nibash,
I understand that you are getting syntax error while using MATLAB function block in Simulink.
The cause of this error is the use of square brackets [ ] for indexing the input vector. Instead, you can try using the following syntax to solve the issue.
function y = fcn(u)
y = c1*(c2/u(2) – c3*u(3) – c4)*exp(-c5/u(2)) + c6*u(1);
end
Hope this resolves your issue.
Thank you.
