MATLAB处理的图像各种gui显示，有sobel，canny、灰度变换等。(MATLAB gui display a variety of image processing, there sobel, canny, gray transformation.)

基于MATLAB的圆检测的图像处理，用到了最小二乘法，和霍夫变换(circle detection)

说明：  rung-kutta 4 he inputs func, x0 and y0 define an IVP y = func(x,y), y(x0) = y0. This provides an approximation to y(x0:h:xn) using fourth-order Runge-Kutta method with step size h

说明：  运用matlab对管道进行传热计算的基础程序(Pipe heat transfer calculation)

基于matlab绘制滚动点阵字幕（跑马灯）.(Draw scrolling dot matrix subtitles (Marquee) based on matlab.)

MNIST数据库处理文件，MNIST数据库是由NIST的专用数据库3和包含手写体数字二值图像的专用数据库1组成的。NIST最初指定SD-3作为他们的训练集，SD-1作为他们的测试集.然而，SD-3比SD-1清洁得多，易于识别(MNIST database processing file)

The traditional power droop controllers are commonly used in distributed generation (DG) units to share the loads among the parallel inverters. However, the parameters of the power transmission and distribution line in microgrid are small and generally presented high resistance-to-inductance (R/X) ratio which will seriously influence the performance of the traditional power droop controller, even leading to instability
