Does anyone know of a Complex to Real FFT that has
been implemented in IDL. (Likewise a corresponding
Real to Complex FFT would also be nice).
Thanks.

I'm probably missing something deep here, but
doesn't this do what you want?

result = FLoat(complex_fft_expression)
result = Imaginary(complex_fft_expression)

Cheers,

David
