Hello !

I have a Matlab function testLectureXML() which has a variable n_component.

I have a GUI with an Appdesigner code too which allow user to brose a file and launch the function testLectureXML(file).

If it's a valid file n_component will be > 0 but if it's an empty file or a non valid file n_component will be = 0. And so i would like to use this variable in my App Designer code. As it is a local variable i don't know how to access to its value : testLectureXML(n_component) ? ou testLectureXML().n_component ?

Thanks for helping
