How does matlab calculate the initial points of a moving average? for example if my timeseries matrix TS is 10x1 and i want 2 and 5 period EMAS then movavg(TS, 2, 5, 'e') will return two 10x1 matrices even though the inital points in theory dont have enough samples to calculate the ema yet.

One nice thing about MATLAB is that you can edit a lot of the functions to see what's inside.
edit movavg
The code is well documented so you should be able to see what's going on.
