Hi Guys, I have got a matrix :378x9. I need to calculate the moving standard deviation with a window size of 180(starting from row one). Can somebody help me please?

I tried but i failed again. I change the question: do you know how to calculate the standard deviation of the matrix of each column till row 180?I think I ll do it per 199 times so

for kk=1:size(X,2) % kk is your column index
s(1:180,kk)=movingstd(X(1:180,kk),180,'f');
end
