3d-fdtd with upm ABC(3d-FDTD in matlab with upml ABC)

本程序实现了语音信号中的信息隐藏，采用DCT和LSB方法。(the information hiding technique is completed with the carrier of voice signal.)

说明：  坐标转换：已知n个点在a,b两坐标系中的坐标值，采用优化方法求转换关系（标准的7参数转换关系，x,y,z的移动，x,y,z的旋转，以及缩放系数）ps:附带空间旋转公式。input: points in A and B。 output：transfer relationship （u,v,w: shit of x,y,z。 a,b,g: rotate of x,y,z 。k：zoom）(Coordinate Transfer:A,B are tow coordinates. This program using optimal method to find the transfer relationship of A and B. input: points in A and B。 output：transfer relationship （u,v,w: shit of x,y,z。 a,b,g: rotate of x,y,z 。k：zoom） )

An implementation of AVL tree very useful for understanding searching in graph.
