Question about preserving variables into GUI

Hello, thanks for reading this,

I have a question about a GUI I set up.

Right now, I have a main.m file that first calls a function where I set up variables so I can put them into a workspace, then I call a GUI so I can manipulate the data and display it. So, my m file looks a bit like:

    create_data
    create_gui

If I manually call the create_data m file within the callback function of the GUI element I want, I can get the result I want, but I don't want to continually call the element, as it wastes memory and cpu time.

Any ideas?

Edit: I tried putting my variables one by one as global variables in my main.m file, but they still couldn't be accessed in my GUI file unless I called the file in the GUI function.

It might be more helpful if you write a simple example.

I've been screwing around with this for awhile, and something I ended up doing was creating a uitable from a workspace variable. The data will be forever constant, so I thought I might as well do it in this case.

After I did this, I just got the data from the uitable in callback functions and I got it to work. So, I guess in the end, I just went with the easiest approach, if not the most robust.

What I was trying to do was take data from a m file and put it into the workspace. Once the variables were in the workspace, I wanted to use those variables in individual callback functions without having to constantly recall the m file that created the variables.

Well you can try this.

a=3;
save('data.mat','a')

This saves your data into .mat file at the same folder. You can upload it back at the function by:

load('data.mat')

Now the data is visible inside the function.
