Inverse Fast Fourier Transform

Compute the inverse FFT to transform frequency domain data back to time/spatial domain. Used to reconstruct signals after frequency domain processing, filtering, or convolution operations. Input is treated as real values representing complex numbers with zero imaginary parts. [Tier: BASIC, Credits: 1]
