CDFTsr8

public CDFTsr8(com.oregondsp.signalProcessing.fft.CDFTsr parent,
               int xoffset,
               int xstride,
               int Xoffset)

Instantiates a new CDFTsr8.

Parameters:

parent - CDFTsr parent instance

xoffset - int specifying offset into the top-level length-N sequence array.

xstride - int specifying the stride of butterflies into the top-level length-N sequence array.

Xoffset - int specifying the offset into the length-N transform array.

Method Detail

link
