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')
