Problem in MATLAB GUI. Invalid or deleted object..
显示 更早的评论
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

st_variogram_pooled doesn't have access to the objects in the GUI so the only way it could delete them is if it uses functions like findall to do horrendous things to a UI.
But unless you can post that function there isn't really anything much we can say on it.

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.
