M.file implementing the formula below using either Mat-lab or octave

In the following, R can take any value between 5 and 6. Work out the value of I for R = 5.00, 5.01, 5.02, ..., and 6. Then find the average value of I. I= 30/(R*(sqrt(R^2+15*pi^2))

r = 5.00:0.01:6.00
for i=1:numel(r)
R=r(i)
I(i)= 30/(R*(sqrt(R^2+15*pi^2)))
end

avg =mean(I)

Hi Samuel,

there is no need to use a loop, if you replace "30/" by "30./" and the "*" and "^2" by ".*" and ".^2" ...
