distance2d_point2line

these are matlab code for communication

说明：  三阶系统的模糊自适应仿真程序，并做了其阶跃响应，隶属度函数等图像(Order Fuzzy adaptive simulation program, and made its step response, the membership function, the image)

神经网络训练根据Kolmogorov定理，输入层有14个节点，所以中间层有29个节点 ％中间层神经元的传递函数为 tansig ％输出层有8个节点，其神经元传递函数为logsig ％训练函数采用traingdx(neural network training under the Kolmogorov theorem, input layer has 14 nodes, Therefore, the intermediate layer has 29% of nodes middle layer neurons in the transfer function for the output layer tansig% have eight nodes, its neuron transfer function for the training function logsig% used traingdx)

此程序主要演示通道间相位误差对DBF旁瓣电平的影响。(This program is mainly to demonstrate of effect of channel phase errors on the sidelobes of DBF.)

说明：  基于matlab的一些三维场景建模代码，个人学习使用。(Some 3D scene modeling code based on MATLAB, personal learning to use.)

灰色系统gm（1，1）模型的matlab程序，可以用于灰色预测。(Grey gm (1,1) model matlab program can be used for gray prediction.)

此程序包括重采样中的最邻近法，双线性内插法，三次卷积法。 (resampling)

In this directory, we can find the eleven files. The relationship between file name and the number of program written in the book is shown in as follows.

本文提出的中值滤波的快速算法的基本思想是：原始数据序列上中值滤波的滑窗在移动过程中，当前窗只要删除其最早的元素，加入窗后的新元素，即成为下一窗的内容。这个只是Matlab里封装的算法代码(In this paper, the median filtering of the fast algorithm for the basic idea is: the original data sequence in the sliding window filtering process in the mobile, the current window as long as the deletion of its first element, adding a new element after the window, that is, the next window content.)
