I have a GUI that runs a program that takes anywhere between a few minutes and a few hours to run and I would like to add a timer to the GUI so I can see how long the program has been running since it started. The program spends the majority of its time in the Symbolic Math Toolbox (~90%), and there are no significant portions of time spent in a loop during execution.
In order to accomplish this (in a way that updates regularly without slowing the original program down), I believe the Parallel Computing Toolbox would have to be utilized, but I don't have any experience with this.
Is there anyone here that might know how this could be accomplished, or if it's even possible?
The timer object in MATLAB (>> help timer) is probably your best bet. Just initialize it when the GUI launches or the program starts and then have it callback to display the runtime.
