bp原理的源程序，可以自由下载，不涉及版权。(bp of the source principle, be free to download, do not involve copyright.)

说明：  用C来编写MEX文件调用MATLAB，很有实用性(MEX using C to write a document called MATLAB, very practical)

说明：  兰伯特投影变换，可将大地坐标与兰伯特坐标系左边相互转换(Lambert projection transformation)

matlab函数scaleif，用于改变度量，详见英文描述( function sim = scaleif(im, newMin, newMax, oldMin, oldMax) Scales an image such that its lowest value attains newMin and it highest value attains newMax. OldMin and oldMax are not necessary but are useful when you don t want to use the true min or max value.)

混沌初始化的PSO，在图像阈值分割方面的应用，自己写的(Chaos initialized PSO, the image threshold segmentation application, write your own)

说明：  小波变换的模极大值判断冲击函数、阶跃函数、三角形函数的奇异性(Wavelet transform modulus maxima to determine the impact of function,step function, the singularity of the triangle function)

automatic number plate using C

个人编写 在simulink里的编写的一个bump路面激励，用来测试悬架的最优阻尼和刚度值(Personal writing in simulink write a bump in the road excitation, damping and stiffness values ​ ​ for the optimal test suspension)

说明：  一阶线性自抗扰控制ESO建模与仿真，模型搭建正确，供大家参考(First order linear ADRC ESO modeling and simulation, the model is built correctly, for your reference)

介绍MATLAB的ppt课件，有助于在短时间里学会运用MATLAB。对数学建模很有帮助。(Introduction MATLAB-ppt courseware, helping in a short time learn to use MATLAB. Useful for mathematical modeling.)
