FFT可以将一个信号的频谱 提取出来，这在频谱分析方面也是经常用的。 (A signal can be extracted from the FFT spectrum, which spectrum analysis is also often used.FFT)

MATLAB界面设计篇，曲线转换按钮，栅格控制按钮，弹出式菜单，多选菜单等32个程序(MATLAB interface design articles, curve conversion button, the grid control buttons, pop-up menu, select the menu more than 32 programs, etc.)

1求矩阵中的 最大值 并返回所在的行数与列数。2判断一组数据满足什么分布，包括泊松分布、正态分布、卡方分布、T分布等。3 检验线性方程组 系数的输入是否有误。(1 find the maximum value and returns the matrix where the rows and columns. 2 to determine what set of data to meet the distribution, including Poisson, normal, chi-square distribution, T distribution. 3 Coefficient of linear equations test input is wrong.)
