本文件是一个SPWM逆变器的仿真源文件，可以在MATLAB7.1中直接运行。设计中PWM Generator采用外部调制信号，并在调制信号中注入了三次谐波，很好的抑制了输出谐波，同时提高了直流电源的利用率。(This document is a SPWM inverter simulation source file, you can directly run MATLAB7.1. Design of PWM Generator external modulation signal, and in the modulation signal into the third harmonic, the output of good harmonic suppression, while improving the utilization of the DC power supply.)

这个描述的频率细化技术，想使用这样的方法，对密集的地方进行放大。(Detailed description of the frequency of this technology, you want to use this method, place of intensive amplification.)

本程序在matlab环境下，基于粒子群算法对pid控制器进行优化控制,从而完成性能更优(The program in matlab environment, based on particle swarm optimization algorithm pid controller to control, thus completing the better performance)

采用四步相移法的图像生成程序，该图像主要用于三维结构光的重构。(use the four step shift method to produce the image,this image is mainly used for the 3d reconstruction)

GrTheory - Graph Theory Toolbox.

这是原始的matlab扩展有限元程序，包括裂纹，夹杂分析，简单易懂(matlab for XFEM)

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)

gentleboost 算法的实现，其主要用在分类与boost和adaboost稍有不同(gentleboost algorithm, which is mainly used in classification and boost and slightly different adaboost)
