Multiple While loops working together simultaniously

I developed a GUI where with multiple push buttons exist. Each push button begins an execution of an infinite loop. When I press a push button the while loop executes fine, but when I press the next push button, the first stops and the next starts, What I need is for all while loops can work simultaneously. I know there is a toolbox in MATLAB called Parallel Computing Toolbox, but i cant figure out how can I use it.

Any help would be appreciated.
