How to find the lowest average of 3 consecutive numbers in a vector ?

Hi,

I need to find the lowest average of consecutive 3-value blocks (ie. (n,n+1,n+2), (n+1,n+2,n+3), (n+2,n+3,n+4) in a vector which has variable length (=number of elements does not have to be a multiple of the block size). Is there an easy way without using nested loops?

Thanks a lot.

[minAvg, minidx] = min((V(1:end-2) + V(2:end-1) + V(3:end))/3);

This returns both the actual average and the location that it starts at.

That's exactly what I was looking for, shame I couldn't figure it out myself:) Thank you!
