how should I plot the y(n)

Z=rand(3000,1);
for n=1:3000 
    x=Z(n);
    y(n)=1-exp(-x);
end

how can I plot the y(n)? I tried cdfplot(y(n)),cdf(x,y(n)), but they are not work

[KALYAN ACHARJYA]

Z=rand(3000,1);
for n=1:3000 
    x=Z(n);
    y(n)=1-exp(-x);
end
cdfplot(y);

Or (Without Loop: Recomended)

x=rand(3000,1);
y=1-exp(-x);
cdfplot(y);

Since this is related to a previous post, I happen to know this is a homework assignment which requires a cdfplot.
