Calculate the time-averaged value every 10 iterations

Hi,
I do the calculation of X (k) 1000x1 in a time loop for t = 1: 10000 (note that X does not have an iteration t) and I want to put a condition when t = 9000 to compute the averaged value (in the time) of X every 10 iterations ot t and when t> = 9000 : 10000
I want to get the size of X average like that 1000x10 without introducing a time iteration t in the variable X
is there a way to do that?

I'm trying to understand your question. I understand that every 10 iterations, you want to display the average computation time of the last 10 iterations. So I would like to recommend you to do something like that:
% create t to go faster
t = NaN(1, 10);
it = 1; % index in t array
for i = 1:10000
tic;
% your code
t(it) = toc; % get the execution time for this sample
% taking into account that i starts with 1
it = it + 1;
% display average time and reset counter
if it == 10
% compute and display average computation time
fprintf('My average computation time = %f\n', mean(t));
it = 1;
end
end
% display last iterations if not already done
if it ~= 1
fprintf('My average computation time = %f\n', mean(t(1:it)));
end
