matlab 画图 三维 函数 等高线，等值线(matlab drawing a three-dimensional function contours, contours)

有认知无线电CR的论文和Matlab代码，进行传统频谱感知算法的能量检测实现与SVM分类算法实现，两个进行对比检测概率性能，还有生成SVM三种核函数的分类检测图与统计三个错误率，得出SVM算法优于能量检测算法(Cognitive radio CR papers and Matlab code, perform traditional spectrum sensing algorithms to achieve energy detection and SVM classification algorithm, two compare the probability of detection performance, as well as generate three types of cores SVM classification detection function diagram with three statistics error rate, obtained SVM algorithm is better than energy detection algorithm)

The histogram of the image gives the frequency of occurrence of the gray level.

自己写的相关性检测和线性预测编码的小程序，可以作为初学者的参考(Write their own correlation detection and the linear predictive coding of small procedures, can be used as a beginner s reference )

小车避障的控制程序，三输入（左右距离之差、前方障碍物距离、与目的地之间偏角）一输出（小车拐角）实现对小车的模糊控制(Car obstacle avoidance control program, three input (about the difference between the distance, distance of obstacles ahead, and the Angle between the destination) the output (the car corners) to realize the fuzzy control of the car)

实现串口的数据采集，使用混沌与分形分析的例程，三相光伏逆变并网的仿真，Relief计算分类权重，MIMO OFDM matlab仿真。( Achieve serial data acquisition, Use Chaos and fractal analysis routines, Three-phase photovoltaic inverter and network simulation, Relief computing classification weight, MIMO OFDM matlab simulation.)

说明：  阵列天线的波束形成程序，为天线方向图的仿真提供便利的工具(Array antenna beam-forming process, for the antenna pattern to provide a convenient tool for the simulation 搜索)

录入图像，可以将一副图像读取并且显示出来(input image，it can read and show the image out )

该代码实现了“大津法”，也就是最大类间方差算法，完全由本人自己编写，结果很好。(The code of the " Otsu method" , which is the Otsu algorithm, written entirely by my own, good results.)

采用DelayTime_MutualInformation互信息法计算混沌时间序列的delaytime的Matlab原程序(used DelayTime_MutualInformation mutual information calculation mixed turbid time series delaytime Matlab original program)
