Sending output from instance to another instance to compute.

So I have very basic knowledge of matlab and have come across an issue. I have a graph set up where I can get different outputs (x and y) depending where I click on it. I would like that to be running that in one window and on the other window, I'd like for the x and y to be changing within a while loop so I get different functions activated. Does that make sense? And if so, is that possible to do?

Example

Instance 1

function... x = y =

---------

Instance 2

while true

if x>0 && y>0

function A

elseif x<0 && y<0

function B

end
