public class TwoDimensionDemo
extends Object

Simple test program for two dimensional Complex FFts. Program forms 2-D complex DataArray filled with Randoms take two centered FFT and compared to reference copy of original. In you run this with VERY large arrays you will run out of default heap memory. If this happens (on Linux) use the -XmxM flag, so

java -Xmx512M TwoDimensionalDemo 4096 4096

will (eventually!!!) take a 4096x4096 complex FFT, provided your system has enough physical memory that it does not swap-thrash its self into the ground!!!
