matlabGUI简单的小程序，求解结构的自由振动频率。结合专业，顺便熟悉编程(matlabGUI simple little program to solve the free vibration frequency of the structure. Combined with professional, by the way familiar with the programming)

这是一个mathlab编写的音乐程序 通过他你可以生动的感受mathlab的神奇魅力！！(This is a progress of music.)

SIMULATION OF INVERTERS

用matlab软件编写感知器算法，实现对样本的分类，样本点为X1(0，0)，X2(0，-1)，X3(-1，0)，X4(-1，-1) (Perceptron Approach with matlab)

matalab程序好用便捷，关于宏观经济，有增长，有波动研究。(matalab program easy to use and convenient, on the macro economy, there is growth, there are fluctuations in research.)

冲击理论指的是计算结构响应的风动荡。这里,结构是一个吊桥,使用连续梁的理论建模。介绍模态耦合模型，尽可能的简单计算横向,纵向和扭转响应。结构的方法是使用。是专为那些已经拥有一些知识领域的随机振动分析和对结构风荷载。(The buffeting theory [1,2] refers to the computation of the response of a structure to wind turbulence. Here, the structure is a suspension bridge, modeled using the theory of continuous beam [3]. The frequency domain approach is used. I did not introduce modal coupling to keep the model as simple as possible. The present script computes the lateral, vertical and torsional response. A multi-modes approach is used. This script is designed for those who already have some knowledge in the field of random vibration analysis and wind loading on structures. )

说明：  短时傅里叶变换，通过加窗函数，切割，做到精细化处理(Short time Fourier transform, through windowing function, cutting, achieve fine processing)

EKF_for_1_Div_UnLine_System 老师写的程序 EKF 效果很好 对EKF的理解有帮助(EKF_for_1_Div_UnLine_System Teachers write the program EKF effect good understanding of the EKF)

很好的QPSK循环谱检测程序，能出结果，且避免了三维搜索，很强大(Cyclic spectrum QPSK good testing procedures, can produce results, and avoid the three-dimensional search, very powerful)
