Hello,
I would like to get the average of some data only if the size of the sample is larger than two. So, if the sample size is smaller or equal to two, then it will not average. Thanks in advance.

if numel(x) > 2
mean_x = mean(x);
end

Don't worry about it. The average of one value is the same as the value. This code works for any array of any size:
theAverage = mean(yourArray(:))
It's not really worth the extra lines of code to have it do it only in the case of 2 or more elements. Why bother? Really.
