Node usage

The FourierTransform1D performs the fast Fourier transform of a single data vector ${\bf x}$. The node arguments are:

Input ports:

x: Row vector to be Fourier transformed

Input parameters:

none

Output ports:

• FreQSpec: This is a vector which contains the frequency spectrum for ${\bf x}$
• AC: This is a scalar which contains the AC component for ${\bf x}$.
• FullComplexSpectrum: This is a vector containing the raw complex values output from the FFT routine for ${\bf x}$.

SEE ALSO: The FFT1D_rows node can be used if you need to use Fourier transform on all the rows of a matrix simultaneously.
