SG-filter

该函数用于二维曲面拟合，能拟合出f=（x，y）的函数图形。(Gridfit is a surface modeling tool, fitting a surface of the form z(x,y) to scattered (or regular) data. As it is not an interpolant, it allows the existence of replicates in your data with no problems.)

分别在2幅灰度图像中加入一定量的高斯噪声和椒盐噪声，噪声强度自定。然后采用3×3的均值滤波器和3×3中值滤波器分别对噪声图像进行处理，给出两种处理方法的峰值信噪比(PSNR)；仿效“中值滤波”的方法，对原图像分别进行“极大值滤波”和“极小值滤波”，对所形成的图像给出说明。(Two gray-scale images a certain amount of Gaussian noise and salt and pepper noise , noise intensity since .)

解决凸优化方面的醉经典工具箱，相信大家都非常熟知这个工具箱，非常棒的工作工具，希望大家下载好好学习！(To solve the problems of convex optimization of the classic drunk toolbox, I believe we are very familiar with this toolbox, very good working tools, I hope you download a good learning!)

说明：  以PSO与三次样条插值结合的移动机器人路径规划算法，主函数为pso.m(Mobile robot path planning algorithm combining PSO and cubic spline interpolation, the main function is pso.m)

说明：  产生一个chirp信号，给出时域及频域特性。利用匹配滤波器进行滤波。如果有延时也能正确滤波。(Generate a chirp signal, given the time domain and frequency domain characteristics. Filtering using matched filter. If there is delay filter can correct.)
