短时能量与过零率，别人写的，好像是可以用的，大家试试啊(Short-term energy and zero-crossing rate, someone else wrote.maybe it can be used, please try it .)

该函数为MATLAB编写，实现功能为中值滤波，中值滤波能更好地保留图像细节，对盐椒噪声有很好的去除效果。(The MATLAB function is prepared to achieve function, median filtering, median filtering can reserve the image detail, and good salt pepper noise removal.)

给出了用迭代法解线性方程组的方法，迭代法是数值分析中一个重要解线性方程组的方法(Proposed by solving linear equations iteration method, the method of numerical analysis of iterative method is an important method of solving linear equations )
