Fields
  NameDescription
Protected fieldconfigColMajor_
Internal MKL configuration manager for column major arrays. The two configurations are identical in all ways except in how they interpret 2D array data.
(Inherited from FFT2DBase.)
Protected fieldconfigRowMajor_
Internal MKL configuration manager for row major arrays. The two configurations are identical in all ways except in how they interpret 2D array data.
(Inherited from FFT2DBase.)

Remarks
The forward FFT is defined to have a negative exponent in the transform with a default scale factor of 1.0.
