The DoubleComplexBackward2DFFT type exposes the following members.
| Name | Description | |
|---|---|---|
| BackwardScaleFactor | Gets or sets the backward scale factor of the FFT; The default is 1.0 | |
| Columns | 
            Gets the number of expected colums in FFT input array
             (Inherited from FFT2DBase)  | |
| Dimension | 
            Gets the FFT dimension; typically either 1, 2 or 3.
             (Inherited from FFT2DBase)  | |
| Direction | 
            Gets the direction of the FFT, either forward or backward.
             (Inherited from FFT2DBase)  | |
| Domain | 
            Gets the forward domain of signal data; either complex or real.
             (Inherited from FFT2DBase)  | |
| Precision | 
            Gets the FFT precision; either float or double
             (Inherited from FFT2DBase)  | |
| Rows | 
            Gets the number of expected rows in FFT input array
