Hi,

I want to compute a function say Rp as of theta and frequency, like Rp(theta, f).

How can I write equation with double loop and secondly how can I plot it like as a function of theta and f ?

The readers cannot guess, why you assume, that loops are required. Maybe this is sufficient already:

theta = linspace(0, 180, 20);

f = linspace(1, 10, 20);

y = Rp(theta, f);

surf(theta, f, y)

function y = Rp(theta, f)

y = sin(theta).' .* cos(f / 5);

end
