I have vector of 10x1. Say 1-10. I want to take harmonic average at a particular point say 5. I want the average to be done in such a way that it will take 2 values on top and below 5 and add 5 itself making a total of 5 samples. How can I write a code for this on matlab?

That is average=(1/3 + 1/4 + 1/5 + 1/6 + 1/7)/5

Using only core MATLAB functions:

x = 1:10;                       % Data
mpx = 5;                        % Midpoint
rngx = 1./x(mpx-2:mpx+2);       % Data Range
mx = mean(rngx);                % Result
