打开文件中图片的简单Matlab程序代码(Open the file in the image of a simple Matlab code)

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

单相全桥PWM整流模型，多次验证表明，该模型动态响应快，静态误差小，完全符合要求。(The single-phase full bridge PWM rectifier model, verified the model many times, fast dynamic response, static error is small, fully meet the requirements.)

主成分分析方法在各个变量之间相关关系研究的基础上，用较少的新变量代替原来较多的变量，而且使这些较少的新变量尽可能多地保留原来较多的变量所反映的信息一种方法。(Principal Component Analysis in the relationship between the various variables on the basis of the study, with fewer new variables replace the original more variable, but made them less a new variable as much as possible to retain the original variables that reflect more information methods)
