I am trying to have the possibility to chose different files (which are functions) and use them with a signal. But I need to have the possibility to change the function without changing the code. I tried this, but I don't know if it works. And I don't know why it doesn't work, because if I call the function directly, it is ok!

Then you should be using function handles, rather than messing about with text representation of function names.

fun = str2func(baseStr);
input_dpd = fun(input_signal.x);

Try replacing your line with eval with the following:
input_dpd = feval(baseStr,input_signal.x);
