i have written the code to acquire data from a data acquisition card , i want know the time taken at each stages to acquire data from one pixel. Eg.- time taken to initialize the channel - time taken to address the channel -time take to read the pixel, -time taken to display the image and i am using USB DAQ, sotime taken by an USB cable for transmission
Note:i tried using tic , toc and could not get proper elapsed time.

Try cputime function instead.
Also tic & toc will provide correct results if no other applications are running simulataneousely on your machine.
