I want to use the two buttons and have the text field change once a folder is selected. Then have the figures and the jpg's save to those respective folders.

This code is really close to done! I would like to be able to use the buttons to choose folders on where to save the formats of the plots that are created during the code. I would also like to have the text box to the right of the buttons update after a folder is selected.

Add property variables

properties
    JPEGSaveLocation
    MATLABFigureSaveLocation
end

add Callback to "JPEG Save Location" pushbutton

app.JPEGSaveLocation = uigetdir('*', 'Select Folder to save JPEG');
JPEGSaveLocationEditField.Value = app.JPEGSaveLocation;

add Callback to "MATLAB Figures Save Location" pushbutton

app.MATLABFigureSaveLocation = uigetdir('*', 'Select Folder to save MATLAB Figures');
MATLABFigureSaveLocationEditField.Value = app.MATLABFigureSaveLocation;

Thanks so much! The field is updating now. Next stop is to get the files to actually save in those locations :)
