Hi all, I'm trying to build a "spectral delay" and to separate the fft analysis into "bands" I'm planning on multyplying the output of rfft by arrays (read with tableread~). These arrays contain as many points as there are fft bins. So my question is: Is there a quick way to populate arrays (1024 points in size) so that between x-value 'a' and x-value 'b' I have a y-value of 1, while the rest of the array is set to 0? I also want to be able control the values of a and b, so the band can be changed dynamically. Any help is very appreciated, as I cannot think of a simple straigthforward way.
Thanks, Andres
