calculate a vector from consecutive vectors without a loop

Hi

I would like to receive the mean value of each 10 consecutive values of a vector. Is it possible to run it without a for loop?

Using a for it would have been:

for ix=1:length(X)-9 mean_X = mean(X(ix:ix+9)) end

Thanks Guy

Totally.. try something like

yourVector = 1:100;
avgWindow = 1/10*ones(1,10); % each value is 1/10

movingAverage = conv(yourVector,avgWindow,'valid')

Compare with

for i = 1:numel(yourVector)-9
  movingAverageLoop(i) = mean(yourVector(i:i+9));
end

Exactly! Thanks!
