Plotting Moving Average of NASDAQ

Hi, I want to plot a Moving Average and a Histogram chart of Nasdaq prices. I created a function called fmean to compute the average of an array's components. Can you show me what I am doing wrong? ..........................................................................
nasdaq = [];
sma = [];
x = 0;
n = 1;
m = 30; %moving avg.
l = length(nasdaq(:,5))
for i = (n+x):(m+x)
sma = fmean(i)
end
x = x+1;
if x = l-m
ts1 = timeseries(sma);
ts1.Name = 'SMA';
ts1.TimeInfo.Units = 'days';
ts1.TimeInfo.StartDate = nasdaq(1:1)
ts1.TimeInfo.Format = 'dd mm yy'
ts2 = timeseries(stock[]);
ts2.Name = 'SMA';
ts2.TimeInfo.Units = 'SMA';
ts2.TimeInfo.StartDate = nasdaq(1:1)
ts2.TimeInfo.Format = 'dd mm yy'
plot(ts1,ts2) grid on
hist(sma)
hist(nasdaq)
end
end

You say: "I created a function called fmean to compute the average of an array's components". Then you call it like this:
sma = fmean(i);
can you tell me how fmean is supposed to compute the average of anything from any array when you're not passing it any array? You're just passing an index. Are you passing the array through some other means such as global or getappdata()?
