int slowFFT | (EST_FVector &real, EST_FVector &imag) |
Basic in-place FFT.
Basic in-place FFT.<para>There's no point actually using this - use fastFFT instead. However, the code in this function closely matches the classic FORTRAN version given in many text books, so is at least easy to follow for new users.</para>
<para>The length of <parameter>real</parameter> and <parameter>imag</parameter> must be the same, and must be a power of 2 (e.g. 128).</para>
