利用经典NEH算法求解工件排序的一种有效算法

国外优秀地震信号分析处理软件的细部功能全英文介绍，提供相关算法的思路及参考文献(seismic signal analysis and processing software in detail functions are all the English introduction, provide ideas and references of the algorithm)

利用最速下降法计算最小曲面的面积，初始条件为0，边界条件为正方形固定边界。(Using steepest descent method to calculate the minimum surface area. Initial condition is 0, while boundary condition is square fixed values.)

CDMA transceiver Code in MATLAB

本程序是一个直接序列扩频仿真，开发环境时在matlab/simulink下进行的，程序简单易懂( This program is a direct sequence spread spectrum simulation, the development environment in matlab/simulink conducted the program easy to understand)

直流伺服电机用MATLAB实现的源代码，伺服系统由具有位置反馈、速度反馈和电流反馈的三闭环结构组成本控制系统采用模糊和PID复合控制，在小偏差时转化为P ID控制，这样就获得了比纯模糊控制更高的稳态精度，有比P ID控制更快的动态响应、更小的超调量。(DC servo motor to achieve with the MATLAB source code, by a position feedback servo system, the speed feedback and current feedback loop structure composed of three of the control system using fuzzy and PID compound control, in a small deviation into the P ID control, so that access to higher than the pure fuzzy control steady-state accuracy, faster than P ID control the dynamic response, smaller overshoot.)

简单的信道化处理信号，输入不同的信号中心频率点会得到不同信号的输出从而分离出输入信号，代码较简单直观(Simple channel processing signal, the input signal different center frequency will be output different signals to separate the input signal, the code is relatively simple and intuitive)

距离函数用matlab实现的距离函数用matlab实现的(Distance function using matlab matlab realize the distance function)

单阵纯方位目标运动分析及双阵纯方位目标运动分析 包括观察者运动与目标运动函数修正 可惜修改两者运动轨迹(Single sensor bearings-only target motion analysis and dual-array bearings-only target motion analysis, including observer movement and target movement function correction Unfortunately, modify both trajectory)

这是重庆大学研究生所用的数理统计教材杨虎编写的数理统计一书的答案(This is chongqing university graduate student of mathematical statistics YangHu teaching material used to write a book of mathematical statistics of the answer )
