Functionality

Calculates the inverse Discrete Fourier Transform of a 1D or 2D array.

Inputs

  • flags_in – DFT_INVERSE, DFT_SCALE, DFT_ROWS, DFT_COMPLEX_OUTPUT, DFT_REAL_OUTPUT
  • nonzeroRows_in – Number of dst rows to process.
  • src_in – Input floating-point real or complex array.

Outputs

  • dst_out – Output array whose size and type depend on the flags.
