If [F, A, B] = fseries (f, x, p, a, b) is a function for solving Fourier coefficients and series, for a given function y = x (x -π) (x -2π) , Fourier series expansion of x ∈ (0, 2π), the correct one is: A、syms x; f=x*(x-pi)*(x-2*pi); [F,A...
A Fourier series is an expansion of a periodic function f(x) in terms of an infinite sum of sines and cosines. Fourier series make use of the orthogonality relationships of the sine and cosine functions. The computation and study of Fourier series is kno
