This function is another tutorial on how to do computer vision type stuff with Octave/Matlab. It shows how to implement Hartley and Zisserman s "DLT" algorithm for estimating a homography from point correspondences

matlab常见方程求根常用方法打包，可以供初学者使用(The matlab common equation Root common method of packaging, for beginners)

有限元的MATLAB程序，该MATLAB程序使用有限元法解决连续体的位移及受力问题。使用限制：节点处可受集中力，每一单元可受一个集中力，每边可受一常值边界力(Finite element MATLAB program, the problem of the MATLAB program using the finite element method to solve the continuum displacement and stress. Use restrictions: nodes under concentrated force, every unit can be subjected to a concentrated force, each side by a constant boundary force )

说明：  EMD matlab实现代码，可以直接用。经验模态分解（Empirical Mode Decomposition，EMD）是由 Huang等人于1998年提出的一种针对非线性、非平稳信号的自适应信号分解算法。(Empirical Mode Decomposition (EMD) is an adaptive signal decomposition algorithm for non-linear and non-stationary signals proposed by Huang et al. in 1998.)
