Does anyone know what algorithm is used for the various FFTs in MATHCAD 15?
Thanks,
Reg
Solved! Go to Solution.
Hi Reg,
The Mathcad 11 user manual (much more informative than manuals of some later versions) says:
cfft Singleton method (Singleton, 1986)
fft Cooley-Tukey (Press et al., 1992)
Success!

Thanks Luc
I realised today that the info on the references is also in the Mathcad 11 handbook. In case you want to look them up:
cfft Singleton, R. Communications of ACM. Vol. 11, no. 11. November, 1986.
fft Press, W.H., W.T. Flannery, S.A.Teukolsky, and B.P.Vetterling. Numerical Recipes in C. Cambridge University Press, New York, 1992.
Success!

Thanks again Luc. Turns out I have a PDF of the Mathcad 11 manual. I will check out the references
