MATLAB: How to Stop Fmincon from GUI

Ravi - I suspect that the example is only meant to provide an idea of how to do this given that you could have created your GUI either using GUIDE or using the programmatic approach. If you are using GUIDE, then you can always pass in hObject as an additional input to the outfun. For example, suppose that you have a start push button to start the optimization where you create the options (for fmincon) and start the optimization. For example,

 function start_pushbutton(hObject, eventdata, handles)
 % do some stuff
 % create the options
 opts = optimoptions(@fmincon,'OutputFcn','{@outfun,hObject});
 % start the optimization

Then, you would change the function signature of your outfun to be

 function stop = outfun(x,optimValues,state,hObject)

Here, it is assumed that you have created the outfun in the same m-file as for your GUI. Now rather than using getappdata (which forces you to have called setappdata to update hObject with the state of stop), I would use guidata to get the handles structure as

 function stop = outfun(x,optimValues,state,hObject)
 stop = false;
 handles = guidata(hObject);
 if isfield(handles,'optimstop')
     stop = handles.optimstop;
 end

And so your stop button callback would look something like

 function stop_pushbutton(hObject, eventdata, handles)
 handles.optimstop = true;
 guidata(hObject,handles);

In the above we set the optimstop field and then save that change to the handles structure.

I haven't tried the above (since I don't have the Optimization Toolbox) but I think that it can be made to work for your implementation.

MATLAB: Geotiffwrite without compression

You almost have it. As the error (and help) indicate, you need to follow 'TiffTags' with a structure when calling geotiffwrite. You can do it in-line, like this:

geotiffwrite('output.TIF',A,R,'GeoKeyDirectoryTag',info.GeoTIFFTags.GeoKeyDirectoryTag,'TiffTags',struct('Compression',Tiff.Compression.None))

or you can first create a TIFF tags structure, like this, for example:

tags.Compression = Tiff.Compression.None;
geotiffwrite('output.TIF',A,R,'GeoKeyDirectoryTag',info.GeoTIFFTags.GeoKeyDirectoryTag,'TiffTags',tags)

In this case, tags has only one field. But you can add others, such as RowsPerStrip, for example, as needed.
