SNDR

说明：  画圆，第一个是标准圆，后面的是加有高斯噪声的圆(Drawcircle, the first is a standard round, followed by the addition of the circular Gaussian noise)

这是一个基于MATLAB编写的BUTTERWORTH滤波器的程序.其中从s域到z域的变换是自己编写的,代替了MATLAB中的系统BUTTERWORTH的系统函数(对于毕业设计的学生,比较有用!!)(based on MATLAB BUTTERWORTH prepared by the filter process. From which z's domain to the domain transform their own preparation, instead of MATLAB system BUTTERWORTH system function (for graduate design students more useful! !))

Flow to compute the incompressible flow in a lid driven cavity

1.采用C均值聚类算法对男女生样本数据中的身高、体重2个特征进行聚类分析，考察不同的类别初始值以及类别数对聚类结果的影响，并以友好的方式图示化结果。 2.采用分级聚类算法对男女生样本数据进行聚类分析。分别尝试采用身高，体重，喜欢数学，喜欢文学，喜欢运动，喜欢模式识别共6个特征，以及身高，体重2个特征进行聚类，对比聚类结果，并以友好的方式图示化结果 (1. The use of C means clustering algorithm on sample data for boys and girls in the height, weight 2 characterized in cluster analysis to investigate the initial values of the different categories and the effect on the number of classes of the clustering result, and in a friendly way of illustration result. 2. Using hierarchical clustering algorithm to male and female students sample data clustering analysis. Try both using height, weight, like math, like literature, like sports, like pattern recognition feature a total of six, as well as height, weight, two features clustering, comparing clustering results, and in a friendly way of illustration of the results)

基于MATLAB平台实现利用FFT计算线性卷积(MATLAB-based platform for the realization of the linear convolution calculation using FFT)

说明：  通过奇异值分解的方法对数字图像进行压缩达到节省存储空间的目的(Compression of digital image by singular value decomposition to save storage space)

说明：  离网逆变器带非线性负载，能发出指令电压谐波，用于实验补偿电压谐波，供参考。(Off-grid inverter with nonlinear load, can send out voltage harmonic instruction, used for experimental compensation voltage harmonic, for reference.)

DIT FFT of sequence and comparison with fft function

经典应用例子，可以供大家学习参考使用，其中大部分是验证过的(Classic application examples)

说明：  针对IEEE14和IEEE6系统的潮流计算程序，可实现对该系统功率和电压分布情况的研究。(According to the power flow calculation program of IEEE14 and IEEE6, the power and voltage distribution of the system can be studied.)
