这是数字视频方面的知识，里面的代码是用MATLAB进行编写的，实现的功能是利用多约束的方法进行目标跟踪，是学习数字视频图像不错的一个例子。(This is a digital video knowledge, which the code is written in MATLAB to achieve the functionality is the use of multi-target tracking method constraints, is learning digital video images of a good example.)

这四个程序分别为高斯消去法、列主元消去法、全主元消去法解线性方程组和Gauss-Jordan消元法求矩阵的逆。 　　程序采用MATLAB语言开发，并在MATLAB6.5下测试通过。(The four procedures were Gaussian elimination, elimination method out PCA, PCA-wide elimination method solution of linear equations and Gauss-Jordan elimination method of inverse matrix. Procedures for the use of MATLAB language development, and under MATLAB6.5 test.)
