public static double[] InverseReal(
Complex[] f,
int n
)
- f Complex
- Samples to be transformed.
- n Int32
- The size of the problem.
DoubleThe original samples.
f should satisfy f[k] = f[n - k]', so just one
half of frequencies array is needed.
f[0] is always real.
If n is even, f[n/2] is real too.
