用于matlab学习，matlab中文参考帮助。希望能够有所帮助(Learning for matlab, matlab Chinese refer to the help. Hope that helps)

实现了用最小二乘法对信号消除趋势项，用Matlab调用Excel中数据，并附实测数据。(achieved using the method of least squares to signal the elimination trend, Matlab called Excel data, with the measured data.)

利用DCT变换对灰度图像进行压缩，求出压缩比；对比不同压缩比的图像。(DCT transform using grayscale image compression, the compression ratio obtained compare different compression ratio of the image.)

说明：  一个图像旋转30度的matlab源代码，实现lena图像的旋转，可直接运行，思路清晰(Rotate an image 30 degrees, matlab code, to achieve lena image rotation, can be directly run, clear)

系统辨识与自适应控制MATLAB仿真一书的代码(code of System identification and adaptive control MATLAB simulation of a )

基于modelcenter和粒子群算法MATLAB最优化解决装箱问题。包含代码、模块、PPT、课程论文(Based on MATLAB modelcenter and particle swarm optimization to solve the packing problem. It contains code modules, PPT, course papers)

说明：  本程序是用MATLAB编写，以后请MATLAB高手多进来切磋，请各位高手指教，看了后给点评价。谢谢！(this program is prepared using MATLAB, after many requests come in MATLAB master skills, the experts advise you please, after reading them to the point evaluation. Thank you!)

This MATLAB FILE contains the complete CODING of plotting a 2 graph on a single graph.

根据逆透视变换原理从交通图像中提取交通参数，可以根据图像的像素坐标计算实际路面的距离，计算车辆的位移，速度等参数(Extract traffic parameters from the traffic image according to the principle of inverse perspective transformation, the actual road distance can be calculated according to the coordinates of the image pixels, the calculation of the displacement of the vehicle speed and other parameters)
