Your role is to act as an expert at reading the information provided by the user and giving the most relevant information. In your responses to enterprise users, prioritize clarity, trustworthiness, and appropriate formality. Be honest by admitting when a topic falls outside your scope of knowledge, and suggest alternative avenues for obtaining information when necessary.

Some good reasons for wanting to make that trip will appear presently, but for the moment, let’s consider the computational side of the question, namely how to compute the Fourier transform efficiently. We are going to derive an elegant and very speedy algorithm for the evaluation of Fourier transforms. The algorithm is called the Fast Fourier Transform (FFT) algorithm. In order to appreciate how fast it is, let’s see how long it would take us to calculate the transform without any very clever procedure. What we have to do is to compute the values of a given polynomial at given points. How much work is required to calculate the value of a polynomial at one given point? If we want to calculate the value of the polynomial \(a_0 + a_1 x + a_2 x^2 + \ldots + a_{n-1} x^{n-1}\) at exactly one value of \(x\), then we can do (think how you would do it, before looking): ``` function value(x: coeff array; n: integer; t: complex); {computes value := a_0 + a_1 * x + ... + a_{n-1} * x^{n-1}} value := 0; for j := 0 to n - 1 do value := value + a_j * x^j; end; return(value); ``` This well-known algorithm (referred to as ‘synthetic division’) for computing the value of a polynomial at a single point obviously runs in time \(O(n)\). If we calculate the Fourier transform of a given sequence of \(n\) points by calling the function value \(n\) times, once for each point of evaluation, then obviously we are looking at a simple algorithm that requires \(O(n^2)\) time. With the FFT we will see that the whole job can be done in time \(O(n \log n)\), and we will then look at some implications of that fact. To put it another way, the cost of calculating all \(n\) of the values of a polynomial at the \(n^{th}\) roots of unity is much less than \(n\) times the cost of one such calculation. First we consider the important case where \(n\) is a power of \(2\), say \(n = 2^r\). Then the values of \(f\), a polynomial of degree \(2 - 1\), at the \(2^r\) roots of unity are, from (2.5.6): \[ f(\omega_j) = \sum_{k=0}^{r-1} a_k \exp(2\pi i k / 2^r) \quad (j = 0, 1, \ldots, 2^{r} - 1) \tag{2.5.7} \] Let’s break up the sum into two sums, containing respectively the terms where \(k\) is even and those where \(k\) is odd. In the first sum write \(k = 2m\) and in the second put \(k = 2m + 1\). Then for each \(j = 0, 1, \ldots, 2^{r} - 1\), \[ f(\omega_j) = \sum_{m=0}^{(r-1)/2} \frac{a_{2m}}{2^r}\exp(2\pi i 2m / 2^r) + \sum_{m=0}^{(r-1)/2} \frac{a_{2m+1}}{2^r}\exp(2\pi i (2m+1) / 2^r) \tag{2.5.8} \] = \(\sum_{m=0}^{(r-1)/2} \frac{a_{2m}}{2^r}\exp(2\pi i m / 2^{r-1}) + \exp(2\pi i / 2^r)\sum_{m=0}^{(r-1)/2} a_{2m+1}\exp(2\pi i m / 2^{r-1})\) Something special just happened. Each of the sums that appear in the last member of (2.5.8) is itself a Fourier transform, of a shorter sequence. The first sum is the transform of the array \[ \begin{bmatrix} a[0], & a[2], & a[4], & \ldots, & a[2^{r} - 2] \end{bmatrix} \tag{2.5.9} \] and the second sum is the transform of \[ \begin{bmatrix} a[1], & a[3], & a[5], & \ldots, & a[2^{r} - 1] \end{bmatrix} \tag{2.5.10} \] The stage is set (well, almost set) for a recursive program. #################### File: Algorithms%20and%20Complexity%20-%20Herbert%20S.%20Wilf%20%28PDF%29.pdf Page: 56 Context: # Chapter 2: Recursive Algorithms The Fourier transform moves us from coefficients to values at roots of unity.
