说明：  COMSOL with Matlab 随机裂隙生成 矩形内建立随机椭圆裂缝(Random elliptical cracks are established within the rectangle)

这是用龙贝格求解数值积分的一种方法，精确性高(This is solved using Romberg numerical integration method, high accuracy)

谱减法，很好的，有不错的注释,这个是我们大作业的源程序，试验过的(Pujianfa，very good!)

Load image and separate RGB and function to do image substraction

最近交互式电源技术，软交换、同步整流、频率固定(Alternating expressions Power technology recently、Softswitch, synchronous rectification, fixed frequency)

MATLAB求解非线性最小二乘法拟合问题 源程序代码(MATLAB for solving nonlinear least-squares fitting of the source code)

这个文件实现了Matlab/Simulink中的三维查找表，对要用到查表的人有帮助，里面用到Reshape函数(This file implements the Matlab/Simulink in a three-dimensional look-up table for use to help people look-up table, which used Reshape function)

add noise matlab code

Calculate a pascal coeficients in a vector of any number and use for a simple filter.
