Class ComplexDoubleFFT_Mixed

java.lang.Object

org.das2.qds.math.fft.jnt.ComplexDoubleFFT_Mixed

public static class ComplexDoubleFFT_Mixed
extends java.lang.Object

Computes FFT's of complex, double precision data of arbitrary length n. This class uses the Mixed Radix method; it has special methods to handle factors 2, 3, 4, 5, 6 and 7, as well as a general factor.

This method appears to be faster than the Radix2 method, when both methods apply, but requires extra storage (which ComplexDoubleFFT_Mixed manages itself).

See ComplexDoubleFFT for details of data layout.
