Hi, this seems to be the last archived version:
Thank you!
So, DoubleFFT_1D.complexForward(double[] a)
expects a sequence of complex numbers as array of double-pairs and
returns with the spectrum in same format?
@SamGinrich Hi, you should also download the javadoc zip too for convenience, here is the un-archive.org-ed link:
http://search.maven.org/remotecontent?filepath=com/github/wendykierp/JTransforms/3.1/JTransforms-3.1-javadoc.jar
Anyway, you're right, except it doesn't return anything, the result is put back/calculated in place in your input array:
public void complexForward(double[] a)
Computes 1D forward DFT of complex data leaving the result in a. Complex number is stored as two double values in sequence: the real and imaginary part, i.e. the size of the input array must be greater or equal 2*n. The physical layout of the input data has to be as follows:a[2*k] = Re[k], a[2*k+1] = Im[k], 0<=k<n

Thank ou very much for the accurate response!
