  • Abstract
    It is shown how a conjugate gradient-fast Fourier transform (CG-FFT) method may be improved by a faster and/or more accurate specialized FFT using a piecewise Lagrange polynomial expansion. The formulas presented allow use of a prime-factor FFT and are more accurate than using a standard FFT by itself.<>
