Popis: In a previous publication, we have used the discrete Fourier transform to compute the binomial coefficients. In the present paper, we extend the previously proposed method to compute the multinomial coefficients, analyse its precision and performance. The other methods, analysed in our previous publication, are also extended to the multinomial case. The FFT method presents the best performance to compute all multinomial coefficients at a given level.
