Landweber迭代正则化的加速，一个很好的正则化方法！(Landweber iterative regularization of the acceleration, a good regularization method!)

水文趋势、突变点分析的matlab相关程序——Lee-Heghinan法、Mann-Kendall法(Hydrological trends point mutation analysis matlab procedures- Lee-Heghinan France, Mann-Kendall method)

基于全局误差的BP神经网络辨识的MATLAB仿真程序，代码有注释(Based on global error of BP neural network identification MATLAB simulation program, code annotated)

随机游走类似布朗运动，就是随机的向各个方向走吧。 虽然代码没什么技术含量，不过产生的图像实在太漂亮了，所以还是贴上来吧。 产生的图像：(Similar to Brownian motion random walk, is random and go in all directions. Although the code is no technical content, but the resulting image is too beautiful, so it is still Tieshanglai it. graphics layer.)

说明：  设计的一个FIR滤波器，可以直接运行的工程，实现低通、高通、带通。可以选择窗函数类型。滤波器阶数，截至频率。(The design of an FIR filter, can directly run the project, to achieve low-pass, high pass, band-pass. You can choose the window function type. Filter order, cutoff frequency.)

该程序在matlab环境下完成DV HOP算法的实现。可算出最短路经算法计算节点间跳数、每个信标节点的校正值并可用用跳数估计距离。(err)

图像阈值分割，为确定图像分割的最佳阈值，基于粒子群优化算法提出了一种多阈值图像分割方法(Image segmentation, image segmentation to determine the optimal threshold value, based on particle swarm optimization algorithm proposes a multi-threshold image segmentation)

关联向量机，很好的工具箱，有用于分类和回归的例子(Relevance vector machine, a good toolbox, there are examples for classification and regression)

说明：  rrt算法在2维和3维环境的规划，均为matlab代码，可用于无人驾驶汽车和移动机器人路径规划(The codes of RRT algorithm in 2 and 3 dimensional environments are matlab codes, which can be used for the path planning of driverless cars and mobile robots)
