Question
Hi Guys, I have got a matrix :378x9. I need to calculate the moving average with a window size of 120(starting from row one). Can somebody help me please? By the way, i need to do it also for the covariance(i mean,"A MOVING COVARIANCE).

Try conv2:
kernel = ones(120,1)/120; output = conv2(yourSignal, kernel, 'valid');
Since the window does not leave the boundaries of your signal, of course the output signal will not have as many elements as your input signal.
