matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第一应用与技巧(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the first application and skill)

说明：  李雅普诺夫指数的计算,适用所有混沌系统 (Lyapunov index calculation, suitable for every system )

利用拉普拉斯变换的思想，通过对数据进行差分，近似得到拉普拉斯变换后的结果，然后检查正负交换的位置，则此为极值点位置，利用此思想得到极值点的位置。(Using the ideas of Laplace transform of the data by the difference approximation get results Laplace transform, and then check the position of the positive and negative exchange, this is the extreme position, take advantage of this thinking of getting extreme points location.)

Dragon Forth (DF) is a powerful tool for creating applications for Palm OS of any complexity. The name Forth means fully compatibility with ANS 94 standard.

i am very tired to describe this is a surprise

用matlab&spss实现聚类分析,源自《计量地理学》（徐建华，华东师范大学）。(Achieve with matlab & spss cluster analysis.)

此程序主要是用来做一些摄像机标定用的，通过它可以测出摄像机的内外参数(The procedure is used to do something with the camera calibration, it can detect the camera's internal and external parameters)

hai it explain how rsa core

输入一组振动数据，灰色预测算法会预测其后的振动趋势(input vibration data,and this algorithm will predict the vibration trend)

关于有限元分析的可以使用的matlab代码，对于FEM编程可以节约不少时间。(Finite element analysis on the matlab code can be used, for FEM programming can save a lot of time.)
