Writing an Equation Help

Hi all,

I'm new to MATLAB and was wondering if anyone could help me insert the following code into MATLAB. (the one the starts with 2pi/N)

Thank you!

Have you written the code for the function ? Is this function designed to work with non-scalar θ I.e. if you call it with:

S(10, linspace(0, 2*pi, 10))  %f = 10, theta is a vector of 10 elements

do you get an error or do you get a vector of 10 elements as output?

The answer to this will change the way to code that summation.
