Expand description

Compute the 2-dimensional discrete Fourier Transform for a Hermitian-symmetric input.

This function computes the FFT of a Hermitian-symmetric complex 2D array, resulting in a real-valued output.

§Arguments

  • x - Input complex-valued 2D array with Hermitian symmetry
  • shape - The shape of the result (optional)
  • axes - The axes along which to compute the FFT (optional)
  • norm - Normalization mode (optional, default is “backward”)

§Returns

  • The real-valued 2D Fourier transform of the Hermitian-symmetric input array
