When I create a function using y-script in the non-linear curve fitter, for example:tau = kn*t;
E1=(exp(-tau)-1+ tau);
Vext = beta*E1;
alpha = 1-exp(-Vext);
the last two charaters always get deleted when I go to the fit window (in this case parenthesis and semicolon).
I have solved this problem by putting in a comment line after the function definiton with some garbage characters in it-but its still sort of annoying. Does anyone know what might cause this?
