{{Short description|Multidimensional fast Fourier transform algorithm}}
The '''vector-radix FFT algorithm''', is a multidimensional [[fast Fourier transform]] (FFT) algorithm, which is a generalization of the ordinary [[Cooley–Tukey FFT algorithm]] that divides the transform dimensions by arbitrary radices. It breaks a multidimensional (MD) [[discrete Fourier transform]] (DFT) down into successively smaller MD DFTs until, ultimately, only trivial MD DFTs need to be evaluated.<ref name="Dudgeon83">{{cite book|last1=Dudgeon|first1=Dan|last2=Russell|first2=Mersereau|title=Multidimensional Digital Signal Processing|date=September 1983|publisher=Prentice Hall|isbn=0136049591|pages=76}}</ref>
