Surfer是地学中常用的一个软件，可以完成等值线图，立体图，流向图等的汇制。其自带的类VBA的开发语言，可以进行二次开发。附件是一些源程序。其中的Jackknifes可以用来对比不同的内差方法，从而得出最优化的内差方法。 (Surfer is the study of a commonly used software, complete contour map, a three-dimensional map, map the flow of the system. Its built-in categories VBA programming languages that can be re-developed. Annex some source. Jackknifes which can be used for comparison within the poor, so as to come up with the most optimal way worse.)

基于牛顿法，现采用编程来计算最优解，matlab程序和简要说明文档。(newton method for optimization)

说明：  fcm算法的matlab实现 模糊聚类的重要过程(fcm matlab algorithm to achieve the important process of fuzzy clustering)

针对弧齿锥齿轮的matlab编程，不过中间还有些问题(Matlab programming for spiral bevel gears, but the middle still have some questions)

它主要介绍了独立分量分析法的步骤以及matlab实现所调用的函数。还有一些例子。(It mainly covers the steps and independent component analysis method to achieve the matlab function call. There are also examples.)

说明：  最小二乘法汇总及matlab仿真的相关程序设计(Simulation of the least square method summary and the relevant programming matlab)

用于学习卡尔曼滤波算法，其中包含了估计值计算和估计误差分析(Study Kalman)

turbo_tst.m 是启动文件，利用bcjr算法进行Turbo码的仿真。同时为了进行比较，还进行了viterbi软译码的仿真。单独的turbo码的仿真主要就是bcjr.m程序，viterbi译码所需的文件比较多一点。(turbo_tst.m the startup files, the use of simulation algorithms bcjr Turbo codes. Meanwhile, in order for comparison, the viterbi decoding software for simulation. Simulation separate turbo code is mainly bcjr.m program, viterbi decoding files needed a little more.)

Newton-Raphson s Method of Rootfinding

经典的隐写算法，包括LSB替换和随机LSB匹配。对于实现简单的信息隐藏最常用的方法，具体用matlab实现。(This is LSB steganography, it includes LSB replacement and random LSB matching. it is most common method for information hiding, and it implement with matlab)
