remove multiples from array

[hiNI]

Hello, 

I am trying to remove multiples of a fundamental frequency from an array of frequency points.  One extra issue with this removal, is that the multiple of the fundamental frequency from the array may be within a range, like +/- 1k.  Any help will be greatly appreciated.

Thanks,

hiNi.

Give this a try.  You want to look at the remainder and then setup a couple of ranges based on the accuracy you want.
