说明：  基本的粒子滤波算法，所用数值模型为带控制量的非线性模型，可修改噪声类型，并可和EKF相比较(Basic particle filter algorithm for the numerical model used to control the volume with the non-linear model, can modify the type of noise can be compared and the EKF)

读取以.dat的数据文件；读取以MIT-BIH数据库的212格式文件(Read the MIT-BIH database 212 format data)

说明：  这是一篇关于移动机器人路径规划方面的资料。很好的(This is a mobile robot path planning. Good)

使用matlab实现三维建模源码，效果非常好，可以用于三维点云数据的建模(Three-dimensional modeling using MATLAB)

matlab实现，附带数据，并有显示结果图的功能，很方便用的(It s implemented using matlab with data as attachment. It also has the function of showing the result and is very convenient to use.)

内含Newtonback.m，Newtonforward.m文件，牛顿插值法，向前向后插值。(Intron Newtonback.m, Newtonforward.m documents, Newton)

说明：  matlab 矩量法编程啊 不错的东西 可以看看啊啊 (method of moments matlab programming ah ah ah good things to look at)

很好用的介绍差分方程和数值微分的PPT，希望对大家有帮助，欢迎下载。(Nice introduces difference equation and numerical differential s PPT. We want to help, welcome to download.)

画出具有不同频率，相位的正弦信号及其DFT序列，并检验信号正交性(Draw different frequencies ,different phase of the sinusoidal signal ,and the DFT sequence, then check the signal orthogonality)
