1Convert A(x) and B(x) from coefficient form to point value form. ( FFT)2Now do the O(n) convolution in point value form to obtain C(x) in point value form, i.e. basically C(x) = A(x) * B(x) in point value form.
3) Now convert C(x) from point value from to coefficient form (Inverse FFT).
What is the fast Fourier transform algorithm?
As the name implies, the Fast Fourier Transform (FFT) is an algorithm that determines Discrete Fourier Transform of an input significantly faster than computing it directly.
In computer science lingo, the FFT reduces the number of computations needed for a problem of size N from O(N^2) to O(NlogN) .29 déc. 2019
What is the FFT algorithm in C++?
FFT is an algorithm to compute DFT in a fast way.
It is generally performed using decimation-in-time (DIT) approach.
Here we give a brief introduction to DIT approach and implementation of the same in C++.
