Timers and Interrupts for Matlab

Question

I would like to know if there are timer and interrupt functions available in Matlab. Do these exist?

I would like to run a sound clip through Matlab and convolve it with an impulse response. As I do this, I need interrupts to switch back and forth between methods. I am using Matlab to prototype an algorithm for a DSP. Thank you.

Answer 1

In general, MATLAB cannot handle interrupts and timers. There are ways of using interrupts using Data Acquisition Toolbox as seen here.

With audio samples in the hard drive, you will not be able to make use of interrupts. MATLAB does not allow you to pipeline the tasks. MATLAB allow does not allow the user to multithread, because bad things can happen. Instead, some of the operations in MATLAB are multithreaded and you get to use in your program. That said, you could finish processing with method 1, get data, and then switch to processing with method 2.

Sample by sample data processing is available in MATLAB. But with audio samples, it is better to use a window.
