Hi,

Sorry in advance because I don't know how should be done so I can't show you any code/script. I have a huge Matlab project written and now I have to validate some function which are inside it using Simulink. These functions are .m files and I know which they are so my main idea was using each function as a block and run whatever I need but I think I can't because they are not in the same path as the simulink project and also they use functions like tf or c2d which are not suported. As a brief example, imagine that you have a function called integrator.m like this:

function y=integrator(u,Ts)
    s=tf('s')
    y=c2d(1/s,Ts)
end

Which is equal to the block if I'm not wrong...

And what I want is having a block which execute my function as follows:

As I told you, this function is in a different folder from the simulink one. I know that the example is so silly but I think it simplifies well my problem without complicating with explanations about my real functions.

Thanks!
