Hello,
How can you compare two vectors with different number of elements? I am just trying to find the equal elements. Thanks!

Your question is fairly vague, but I have a feeling that either the ismember() command or the intersect() command will help you do what you want.

Sorry I wasn't clearer. And yes, intersect was what I was looking for. Thank you!

Let a and b be two arrays(or vectors). L=length(a), M=length(b).Suppose L>M, pad_zero=L-M; now b=[b zeros(1,pad_zero)]; c=a-b; now you can find the indices of the zero elements excluding the last pad_zero elements. These are your desired indices. Hope it helps.

Uh ... isn't it a lot easier to just use [c ia ib] = intersect(a,b)?

yes it is indeed, I was just trying out an alternative....
