Computes 2D FFT with memory efficiency in mind

This function performs a 2D FFT with optimized memory usage, which is particularly beneficial for large arrays.

§Arguments

  • input - Input 2D array
  • shape - Optional shape for the output
  • mode - Whether to compute forward or inverse FFT
  • normalize - Whether to normalize the result

§Returns

  • Result with the processed 2D array

§Errors

Returns an error if the computation fails.
