How plot MOVING AVERAGE?

Hi guys! I need your help!

I'm trying to plot a moving average by taking the file from "Yahoo Finance" I've already seen the function "tsmovavg" but that doesn't helped me.

From MATLAB help I've seen the following example about the different types of MA:

load disney.mat
weekly = toweekly(dis);
dates = (weekly.dates);
price = fts2mat(weekly.CLOSE);
window_size = 12;
simple = tsmovavg(price,'s',window_size,1);
exp = tsmovavg(price,'e',window_size,1);
tri = tsmovavg(price,'t',window_size,1);
semi_gaussian = [0.026 0.045 0.071 0.1 0.12 0.138];
semi_gaussian = [semi_gaussian fliplr(semi_gaussian)];
weighted = tsmovavg(price,'w',semi_gaussian,1);
modif = tsmovavg(price,'m',window_size,1);
plot(dates,price,...
    dates,simple,...
    dates,exp,...
    dates,tri,...
    dates,weighted,...
    dates,modif)
datetick
legend('Stock Price','Simple','Exponential','Triangular','Weighted',...
    'Modified','Location','NorthWest')
title('Disney Weekly Price & Moving Averages')

However I have some problems about setting the problem

Thanks for your consideration and any help!!!

I want take a time series from Yahoo finance and then draw the moving average (for example for 20 lags) of this time series.

Thanks
