Function to ask a MATLAB program to wait for an event before continuing execution

I want to use two MATLAB sessions on the same machine to run two different programs. My problem is that at some stage, the first program must use some results of the second program. So, is there a function that may apply to the first program to expect a step up the appearance of a result.

The easiest way to solve this is to have process #1 create a file in a place accessible by both process #1 and process #2. Process #1 runs until it gets to the point where it needs the results from process #2. At this point, it goes into a loop while exist(myFileName),pause(1),end, which makes it wait as long as the file exists, checking every second for whether the file's gone. Process #2 removes the file as soon as it's done writing out the results, at which point process #1 continues.
