Loading a surface fit in a GUI

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

the solution is to type

%#function sfit

before loading the file

Hi,

I am having the same issue, but then using a LinearModel.fit. My GUI runs fine using Matlab, but on a computer without Matlab, the GUI is not able to load the LinearModel.fit. Is there a command to put in the GUI so my GUI will load the LinearModel?
