the data is from a force platform and im trying to calculate jump height. to do this i need to count the number of times the force was zero, however the participant got of the force platform before the software finished recording so the data force goes back to zero at the end. i want to discount this second lot of zeros.

It would help to have your data.
This approach will give you the starting index of the last string of zero values:
v = [zeros(1, 10) rand(1, 20) zeros(1, 5)];
vf = fliplr(v);
[~,idx] = max(vf > 0);
LastZeroStart = numel(v) - idx + 2;
I wrote it in several lines to demonstrate how it works.
