Hello from France

I think it would be very interesting to have the fft() and its inverse ifft() implemented.
This is very useful in data processing in many fields.

Have you thought to implement these functions ?

Best regards and thanks for the work done

Take a look at this for instance Matlab C++ Math plugin

That question has not been answered. Who cares Matlab, who cares another "lib" ?
We desperately need the universal "fft", i.e: fft/cfft and the inverse ifft/icfft,
name universaly that way. The code is free and there is one even faster than the
hyperfast Mathcad. We need it coded in the f(x) menu. As well, it must accept
vector and matrix . The twin problem with "fft" is the need for the vectorising
operator ... how "vectorise" is coded in Mathcad ?

No problem to make "fft" [1D,2D] make it "book style" as Smath function but will
be slow, of limited end use on large matrix [image ...].

That reminds me Xavier distributed *.dll of FFTW for Mathcad 11
Not worth the effort, hardly faster than the native Mathcad "fft"
