角锥体法后方交会，利用共线条件方程解算外方位元素(Resection pyramid method, the use of collinearity equation solver exterior orientation elements)

基于LBP的图像特征提取算法,检索效果大家可是自己实现试试，这种算法还是比较有优势的，但还需要很多改进(image retrieval algorithm based on LBP)

主要详细的介绍了matlab的一些使用方法，这对于一个新手而言绝对很有帮助(Mainly a detailed description of some use matlab, which is definitely helpful for a novice)

OMP algorithm to implement compressive sensing algorithms

已知一个LTI系统的差分方程为： y[n]-1.143*y[n-1]+0.4128*y[n-2]=0.0675*x[n]+0.1349*x[n-1]+0.0675*x[n-2] 初始条件y(-1)=1,y(-2)=2，输入x(n)=u(n)，计算系统的零输入响应 (known LTI system of a differential equation : y [n]-1.143* y [n-1] 0.4128* y [n-2] x = 0.0675* 0.1349 [n]* x [n-1] 0.0675* x [n-2] initial conditions y (1) = 1, y (2) = 2, input x (n) = u (n), we calculate the zero input response)
