Expand description
RDFT codelet generation — R2HC and HC2R.
Generates optimized codelets matching the hand-written signatures in
oxifft/src/rdft/codelets/mod.rs:
r2hc_N<T: Float>(x: &[T], y: &mut [Complex<T>])— real to half-complexhc2r_N<T: Float>(y: &[Complex<T>], x: &mut [T])— half-complex to real (unnormalized)
R2HC output stores N/2+1 complex bins: Y[0]…Y[N/2]. Y[0].im and Y[N/2].im are always zero for real inputs. HC2R is the exact inverse butterfly; caller divides by N for true inverse.
