- bits is a power of two such that 2^b is the number
of samples.Method Detail |

public static void main(java.lang.String[] argv)
public void doFFT(double[] xr, double[] xi, boolean invFlag)
double
- [] xr is the real part of the data to be transformeddouble
- [] xi is the imaginary part of the data to be transformed
(normally zero unless inverse transofrm is effect).boolean
- invFlag which is true if inverse transform is being
applied. false for a forward transform.
