MATLAB: How to extract from a table 1 value each 5 or each 10

Question

I'm new to matlab, I'd like to know how to extract a value from a table every 5 or 10, and in doing so create a new table 5 times or 10 times smaller.

(I have some measures taken with a rate too high).

Thank you in advance guys!!

Answer 1

A = rand(100,1);
A_smaller = A(1:5:end)

If you mean something else than this regular sampling, please a lot more detail (and perhaps a small example) of what you mean.
