交流BUCKBOOST拓扑的MATLAB仿真 (AC_BUCK_BOOST )

DESCRIPTION: This Matlab algorithm performs many tasks associated with power system analysis. First, it has the ability to perform both fully coupled and dc power flow analysis. Second, it has the ability to create measurements (with user-defined error) to be used as input for state estimation. Third, it has the ability to perform state estimation - allowing the user to examine how the placement of measurement devices as well as magnitude of distibution of measurement error affect the discrepency between power flow and state estimation results. In essence, it provides the user with a complete package for the study of both power flow and state estimation in n-bus power systems.

MATLAB实现huffman编码,可以自由改变输入(Convert a color image into a grayscale)

一些基本的語法練習，可以拿來實際應用，包含了註解與程式(Some basic grammar exercises, can be used to practical applications, including annotations and programs)

此程序主要用于处理轴承和齿轮故障，先进行傅里叶变换，然后在信号频域内做频谱自相关，通过频谱自相关，可以识别频谱中的周期性调制信息(This procedure is mainly used for processing the bearing and gear failure, Fourier transform first, and then the signal in the frequency domain spectrum autocorrelation, through spectrum autocorrelation, can identify the periodic modulation in the spectrum of information)
