Figure Exporter is a simple interface that helps you formatting and exporting your plots in a simple way.
First you need to download and install the GUI Layout Toolbox at https://www.mathworks.com/matlabcentral/fileexchange/27758-gui-layout-toolbox
Then you can execute the testme.m file in Matlab to test the application. As you can see in this file, the tool only requires the handle to the axes you want to export as input.
Basically, you can run the tool with the following command to export the current axes image:
FigExporter(gca);
