QRalgorithm

不调用MATLAB本身的神经网络工具箱实现两层神经网络(creat a simple two layers ANN without using the ANN toolbox of MATLAB )

这是一个在MATLABR2010a的环境下搭建的异步发电机不带负载的仿真模型。运行良好，波形比较理想。(This is a simulation model built at ambient MATLAB 2010 asynchronous generator with no load. Running well, the ideal waveform.)

OFDM系统的简单代码，便于初学者理解，设置了N=128个信道，传送1,0的随机数，并加入fading和AWGN noise(OFDM system simple codes, for beginners to be understood that the channel 128 is provided, fading and AWGN noise added)

说明：  K-means聚类，将多个点根据各自的坐标，一定的算法分析，在matlab上可以看到聚类结果图像，帮助人们更好的分类不同的点，确定选址问题(K-means clustering, according to the coordinates of multiple points, a certain algorithm analysis, in Matlab can see the clustering results image, help people better classify different points, determine the location problem.)

说明：  1.编制一个计算两个序列线性卷积的程序，计算y(i)=x(m)*h(n)，分别绘制x(m)和h(n)，以及线性卷积结果y(i)的图形，使用matlab自带的conv函数来验证结果。 2.使用matlab自带的FFT和iFFT程序，实现线性卷积的快速计算，并对计算结果进行绘制。(1. Make a program to calculate the linear convolution of two sequences, calculate y (I) = x (m) * H (n), draw the graph of X (m) and H (n), and the graph of the linear convolution result y (I), and use the conv function of MATLAB to verify the result. 2. The FFT and IFFT programs of MATLAB are used to realize the fast calculation of linear convolution and draw the calculation results.)

本程序的功能是用牛顿-拉夫逊法进行潮流计算(This procedure is the function of Newton- Raphson power flow calculation method)

基于MATLAB_SIMULINK交流变频调速系统的仿真研究，对spwm交流变频调速进行仿真(spwm)

greedy_method.m为为贪婪算法程序。所得结果为局部最优，可能不是全局最优的。(greedy_method.m greedy algorithm program. The results obtained for the local optimum, may not be globally optimal.)

检测从键盘输入字符。用到了fiugre的 currentcharacter 属性，figure还有一个 currentkey 属性。这两个属性都能检测键盘输入，不过还是有不小区别，可以试一下。(Detection input from the keyboard characters. Use of the fiugre' s ' currentcharacter' property, figure there is a ' currentkey' property. These two properties can be detected keyboard input, but there are still no small difference, you can try.)

分别建立命令文件和函数文件 转换想x，y的值 求一元二次方程的根(The establishment of a command file and function file Conversion to x, y values Seeking the root of one dollar a quadratic equation)
