本文是编程实现图像的统计直方图，以利于了解直方图修正(This is the image histogram programming to help inform the histogram revised)

this code about optimization

分别利用fisher判别法和近邻法对一组声呐数据进行模式识别，计算分类的正确率(Respectively, and the use of fisher discriminant method nearest neighbor method sonar data to a set of pattern recognition, to calculate the correct classification rate)

雷达仿真软件，下载下来在vs中可直接编译运行(Radar simulation can be directly compiled to run)

说明：  双音频按键识别 背景： 打电话拨号时，每次按键会发出不同的声音，这些声音实际上是由一些固定频率的正弦信号合成的。因为每个按键声音包含两个不同频率的正弦信号，因此也被称为“双音频”信号，简记为DTMF。这相当于是对不同键位用‘音频’进行了编码，如同计算机领域中用数字0和1对处理对象（包括键盘）进行编码。(Two-tone buttons identify Background: When you call dial, each key emits different sounds, which is actually made up of some fixed frequency sinusoidal signal synthesis. Because the sound of each key contains two sinusoidal signals of different frequencies, it is also known as &quot two-tone&quot signal, abbreviated as DTMF. This is equivalent to different keys using the ' audio' encoded, as the computer industry with the numbers 0 and 1 pair of processing object (including the keyboard) to be encoded.)

仿真为单相并网逆变器的仿真模型，使用matlab进行搭建，使用无差拍控制的方法，希望进行探讨(Simulation of single-phase grid-connected inverter simulation model using matlab to build, using deadbeat control, and I hope to explore)

说明：  33节点配电网仿真模型，可用于电力系统分析，潮流计算、短路计算(33 nodes distribution network simulation model and can be used for power system analysis, power flow calculation, short circuit calculation)

在matlab下运行，产生标准均匀分布，正态分布和指数分布的随机数发生器程序。(In matlab running, generate standard uniform, normal and exponential distribution random number generator program.)
