set(handles.scale_box,'enable','on'); % This line works
st_scale = st_variogram_pooled(data_train); % external code to calculate scale
set(handles.scale_box, 'String', st_scale);% This line gives the above error
% All set commands give the error from here on in the callback

Actually I figured this out myself. There was a "close all;" command in the function 'st_variogram_pooled' and it was deleting all the objects in the GUI.

According to me, it seems like the function 'st_variogram_pooled(data_train)' is calculating the scale in numeric format, so the value of variable 'st_scale' will be in numeric format and you are trying to put it into string format for GUI field 'scale_box' in next set() command.
Try to use:
set(handles.scale_box, 'String', num2str(st_scale));
same for all other set commands. Convert num into string using num2str command as I shown above.

There was no problem with set command. I have explained the problem in a comment to my question. Thank You for answering.
