* This subroutine computes a split-radix IFFT for real data
|

* It is a C version of the FORTRAN program in "Real-Valued
|
|
* Fast Fourier Transform Algorithms" by H. Sorensen et al.
|
|
* in Trans. on ASSP, June 1987, pp. 849-863. It uses half

|
|
* *
|
|
* Length is n = 2^(fftOrder). Decimation in frequency. Result is
|
|
* in place. It uses table look-up for the trigonometric functions.
|
|
*
|
|
* Input order: *
|
|
* (Re[0], Re[1], ... Re[n/2], Im[n/2 - 1]...Im[1])
|
|
* Output order:
|
|
* (x[0], x[1], ... x[n - 1])
|
|
* The output transform exhibit hermitian symmetry (i.e. real
|
|
* part of transform is even while imaginary part is odd).
|
|
* Hence Im[0] = Im[n/2] = 0; and n memory locations suffice.
