MATLAB: Loading a surface fit in a GUI

Question

I have a little problem with this code, it runs without any problems before compiling it using the deploy tol but when i compile it an error massage came which means that

 %fit33 is originally a sfit and cant be treated as an object
  and error using feval
here is the code 
 load fit33
 SPS=feval(fit33,0.6,1);

i am Asking if there is any method to load fit33 and treat it as a surface fit then use feval, or is there is any other function rather than feval to evaluate the surface fit at this point

Thanks in Advance

Answer 1

the solution is to type

%#function sfit

before loading the file
