Trying to run two functions simultaniously- acquisition of data from virtual COM port and displaying pictures

hello,

I am working on my final project from school. I'm trying to acquire data and display it on my gui (heart beat signal) and simultaniously display pictures on a different screen. When I tried to do that in different ways, without parallelism, I got big delays which hurt my analysis. Can anyone please explain to me how I can make it work with parallel computing toolbox? I tried to open a job and batch my daq function but it didnt seem to do anything. the code I used: job= batch('daqdov') wait(job);

load(job,'rawd');

picdisptry; plot(rawd,'*');

delete(job);

while daqdov and picdisptry are two of the functions i need to run together.

thanks
