cummulative distribution

I wanna write a script with using matlab, which calculates the cummulative distribution function of the given input but i don't have any idea about this.I know that there is prepared function in matlab (cdf) but I have to write because this is homework.Thanks

Consider you generate gaussian random variables x and want to find cdf;

This is the script;

x=randn(10000,1); % generate 10000 gaussian samples

%find maxm of and minimum of x

P=max(x)-min(x);

L=min(x)/1000:max(x);

y=hist(x,L) % generate histogram;

z=cumsum; % cdf

plot(L,z);

that's it
