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

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

Arguments

• x - Input complex-valued N-dimensional 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”)
• overwrite_x - Whether to overwrite the input array (optional)
• workers - Number of workers to use for parallel computation (optional)

Returns

• The real-valued N-dimensional Fourier transform of the Hermitian-symmetric input array
