converting variable sampling rate to fixed rate - cban...@gmail.com - Jul 17 8:17:28 2008



I am working with a signal that was sampled at a variable rate and consists of an array of
values and a separate array of sample times.  The sample intervals are random and are not
multiples of any common value.  

I need to convert this signal to a single array with a known, fixed sampling rate.  Does anyone
have suggestions as to how I would go about this?  

Thanks, 
Chris

Never mind, I figured it out.  Using the interp1 function with an
appropriate xi array solved my problem.
