The DoubleForward1DFFT type exposes the following members.
Name | Description | |
---|---|---|
DoubleForward1DFFT(FFTBase) | Constructs a forward 1D FFT instance by copying the configuration from another FFT instance. | |
DoubleForward1DFFT(Int32) | Constructs a forward 1D FFT instance for double real signal vectors. |
Name | Description | |
