从网络上搜集的决策树源码，包括C4_5、ID3、CART_iris三个源码，供大家一起学习研究。(Decision tree collected from the network source, including C4_5, ID3, CART_iris 3 source for study and research with everyone.)

一个 天线的MATLAB 代码，是在国外的网站下的(Antenna)

完整的makay的LDPC码生成和译码的程序。(Complete makay the LDPC code generation and decoding procedures.)

说明：  读取地震数据的道头字并画出剖面图, 没有读出所有的道头，只读取了几个角为重要的(read headers of seismic data and draw the profile)

用于abaqus各向同性线弹性梁 单轴拉伸 子程序umat(FOR ISOTROPIC ELASTICITY)

这两个代码是用贝努利法求方程的最大实根和最小实根，方程只要是标准形式输入参数就可以调用此MATLAB函数(These two functions which are writtern by Matlab can solve out the max and min root through the Benvli method.)

空间信号的波达方向（Direction of Arrival，简称DOA）估计作为阵列信号处理研究的一个主要课题，在近些年来越来越得到大量的关注和研究。它可实现对空间中信源信号的准确的角度估计，实现信源方位等参数的具体精确检测，并且还具有很高的分辨力。这些特性使得DOA估计在声呐、通信及雷达等多种领域具有广阔的应用和发展前景。此程序为面阵中二维角度估计算法程序。(direction of arrival,usually called DOA,has been an important subject recently.This program contains unitary esprit)

基于MATLAB的数字信号处理的源程序，非常有用(MATLAB-based digital signal processing of the source, very useful)

FDM method in Laplace problem

模糊控制课程作业，针对给定的系统（传递函数）搭建了Simulink平台，对比了模糊控制与PID控制的效果，可通过选取不同的模糊逻辑规则与参数调节仿真结果。(In the course assignment of fuzzy control, a Simulink platform is built for a given system (transfer function). The effects of fuzzy control and PID control are compared. The simulation results can be adjusted by choosing different fuzzy logic rules and parameters.)
