    • Field Summary

      Fields 
      Modifier and Type Field Description
      static long None
      Computes the FFT result with no scaling.
      static long Size
      Scales the FFT result with reciprocal of the total FFT size over all transformed dimensions.
      static long Unitary
      Scales the FFT result with reciprocal square root of the total FFT size over all transformed dimensions, resulting in signal strength conserving transformation.
