start app by doubleclicking mat-file with custom extension

An application which was greated using GUIDE can save *.mat files with a cusom extension, like *.MyExtension. What I want is, that I doubleclick in the windows explorer such a file, which will: 1. open my application (probably some settings in windows) 2. pass the file path to the application, so that the data can be loaded. Can someone help me on this?

When you say "open my application", would that be a compiled application, or do you mean that MATLAB should be opened and it should run your GUIDE .m, preferably somehow sending in the name of the file that was clicked on?
