预测分类，针对目标样本进行训练比对，预测有可能发生的情况(Predictive classification, target training samples compared to predicted situation may occur)

说明：  本例用matlab解决了数学建模中飞机精确定位问题。使用了优化函数‘constr’解决。（请在matlab 6.5以下运行）(Using matlab to solve this case, the mathematical modeling of precise positioning of the aircraft. The use of optimized function ' constr' solution. (Please run the following in matlab 6.5))

说明：  其主要内容包括：MATLAB 入门及基本操作，数 组、矩阵的使用及数据可视化方法，脚步文件及函数的编写，以及仿 真、图形用户界面入门等。(Its main contents include: MATLAB Introduction and basic operation, array, matrix use and data visualization methods, the pace of preparation of documents and functions, as well as simulation, graphical user interface, such as entry.)

music算法进行雷达信号方向角的谱估计，比较详细。有仿真图形。(music algorithm of radar signal spectrum DOA estimates, in more detail. There are simulation graphics.)

matlab仿真程序小练习，五个小程序的练习，很有参考的价值(matlab simulation program of small exercises, five small program of exercises, the value of a good reference)

绘制出齿轮网格，计算出齿轮应力，并画出两齿轮三维接触图。(Drawing out the gear mesh, calculate the gear stress, and draw two-dimensional contact map gear.)

This file contains the implementation of AM modulation DSC-SB. Modulated signal is obtained in AM DSB-SC

惯性导航系统通常由惯性测量装置、计算机、控制显示器等组成。惯性测量装置包括加速度计和陀螺仪,又称惯性导航组合。3个自由度陀螺仪用来测量飞行器的三个转动运动；3个加速度计用来测量飞行器的3个平移运动的加速度。计算机根据测得的加速度信号计算出飞行器的速度和位置数据。控制显示器显示各种导航参数(Inertial navigation system usually means from the inertial measurement, control, computer monitor etc.. Inertial measurement device comprises accelerometer and gyroscope, also called inertial navigation. 3 degree of freedom gyro is used to measure the vehicle three rotational motion 3 accelerometers used 3 translational motion measurement vehicle acceleration. The computer according to the acceleration signal measured to calculate the vehicle speed and position data. All kinds of navigation parameter control display)

说明：  可以实现turbo码不同码率编码译码结果。(It can realize the decoding results of Turbo codes with different code rates.)
