I'm writing a GUI without guide or app designer recently.

The question I have is that I don't know how to pass data between different callback functions.

My requirement is load a .mat file in the callback function of one button, and data in this .mat file can be used in other functions.

function btnRtSet_ButtonPushed(hObject,eventdata,handles)
    load('Net.mat');
    InitNet;
end%btnRtSet_Callback

This function is the callback of a button, and InitNet is a .m file.

Data in Net.mat are as follows,

Link struct

Conn struct

And functions in InitNet are very basic and simple.

Here are warnings after running,

Error using load
Attempt to add "Conn" to a static workspace.
