MATLAB GUI Interconnection procedure??

I have a gui from a vendor for which i cannot access the source code. and i have made another gui to add the insufficiency in the vendor-gui.Is it possible to link the first gui to my gui.Like can i give in commands from my gui to input in gui 1 and give the output from my gui??

What modules/ reference material should i look to gain more knowledge???

How do you know that your code will improve or supplement the vendor's code if you don't have the vendor's source code and thus don't know the variable names or names (tags) of the various handles on the GUI? How did you even test your code - your other GUI that you've already made? I think you need the source code or else you need to rewrite it completely on your own.
