You might find the getting started guide very useful, second and third chapters are a good investment.

% Sample data
x = 1:100;
y = sin(x);

% Take every 10 
y(1:10:100)

If you have a Signal Processing toolbox, you can use downsample function

Try this on the signal you have generated to take every 5th sample:

subSampledSignal = yourSignal(1:5:end);

Adapt as needed.
