Problem 45480. Find the Fourier coefficients of a periodic function

For the a given periodic function, f, calculate the first N Fourier coefficients. The inputs to your function must be one period of the function f, number of harmonics, N, the period T in seconds, and sampling period, Ts, in seconds/sample, and type, which can be 'real' or 'complex'. If type is 'real', return real coefficients in a 2x(N+1) matrix, where first row is the cosine terms. If type is 'complex', return complex coefficients in a 1x(2*N+1) matrix.
