I want to know if there is an easy way to obtain a Fourier Transform form
a vector or an array (just like fft does), but with a more density base.
I mean, if I have a vector of 512 of length, I want the Fourier Transform to
be 1024, or 2048, etc, in length (de u domain). Or should I modify the
fft C code to do that?
If I want to modify the precision of the fft function, which parameter of the .Machine option do I modify, and how?
Thank you for your help.
