FRFT的程序 与FFT相比有自由度的优势 在金融期权定价中可以应用-Fractional Fast Fourier Transform(FRFT)

For given A/B returns conv(A,B) (non-circular). Subroutine can automatically choose between three implementations: straightforward O(M*N) formula for very small N (or M), overlap-add algorithm for cases where max(M,N) is significantly large
