Hi Roberson, thanks for your answer but here we cannot calculate for the condition of 1 to N that's been mentioned in the equation. Also it should take the values for the set of values for rho and h as given in the equation. If you come across the answer pls help me out.

Is there a reason why rho or h would not be length N?
If there is a reason why they are longer then use
pequiv = a * sum(rho(1:N) .* h(1:N));
You could put it all in a function if you really wanted, but it seems a bit simple:
pequiv = @(N,a,rho,h) a * sum(rho(1:N) .* h(1:N));
