Implement primitive realloc(3) functionality.

吉布斯定轨法。 输入：轨道上任意三个点的位矢(R1,R2,R3)； 输出：质点在R2端点时的速度V2；ierr是个判断符号，返回的ierr是零的话，就说明‘R1,R2,R3’共面，如果ierr是1的话说明‘R1,R2,R3’不共面(正常情 况下，要构成轨道的话，‘R1,R2,R3’一定共面 ，即ierr是零，如果ierr是1的话说明输入的‘R1,R2,R3’不共面不能构成轨道。 此函数用于：任意给定三个空间共面的向量，可以确定质点在R2处的速度V2，也就得到了轨道上的一个状态向量(R2,V2),调用前面的函数就可以确定其轨道，及任意时刻的状态。(Gibbs set the track method. Input: track any three points of the bit vector (R1, R2, R3) output: particle at R2 endpoint speed V2, ierr is a judgment symbol, The ierr that is returned is zero, then, it means' of R1, R2,, R3, ' coplanar, if ierr is 1, then description' of R1, R2,, R3, ' not a total surface (under normal circumstances, you want to constitute a track, then,' of R1, R2, R3, ' a certain total surface, ierr is zero, if ierr is an instructions to enter the words ' of R1, R2, R3' coplanarity can not constitute a track. This function is used: for any given three space vector of the surface, can determine the particle at the speed V2, R2 also track a state vector (R2, V2), call the previous function can determine its orbit, and at any time of the state.)

多用户MIMO中的块对角化，主要用来消除用户间的干扰(Block Diagonalization for Multi-User MIMO)

基于matlab的摄像机标定代码，精度很高，可直接用于程序。(Camera Calibration Based on matlab code, high precision, can be used for procedures.)

用matlab实现基于时间序列的最小二乘支持向量机预测，代码简单易懂，适合初学者使用(achieve the lssvm regression based on time series using matlab)

Modeling an Inverted Pendulum in Simulink using PID

ekf,ukf等滤波器的工具箱，非常实用，适合初级，中级，高级人群使用(ekf, ukf toolbox so the filter is very useful for beginner, intermediate and advanced groups to use)

说明：  用非matlab工具箱实现直方图均衡化。(With non-realization of histogram equalization matlab toolbox.)

说明：  经典的同步算法，即最大似然同步算法，对于开发3G系统很有效( a good synchronization program named as ML(the maximum likelihood method),it is useful for you to develop the 3G system.)

本代码是用来检测图像的局部不变特征的，主要参考DAVID G. LOWE的sift的论文。变成工具是matlab。(This code is used to detect the image of local invariant features, the main reference DAVID G. Lowe s sift paper. Become a tool is Matlab.)
