Thanks,

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!

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
