利用DFT分析离散信号频谱的实验。利用FFT分析信号 x[k]=cos(3pik/8 +pi/4 ) 的频谱；确定DFT计算的参数，绘出其频谱；并进行理论值与计算值比较。(DFT analysis of discrete signal spectrum utilization experiments. Analysis using FFT signal x [k] = cos (3pik/8+ pi/4) of the spectrum determine the parameters of DFT calculations, draw its spectrum and comparing the theoretical and calculated values.)

非负矩阵分解，测试cbcl,orl,swimmer数据集程序，画图程序(NMF, test cbcl, orl, swimmer data collection program, drawing program)

说明：  在matlab2019B中，已经将princomp函数改为了pca函数，功能相同，函数名改变，所以如果要使用，记得将老版本的代码中的princomp改为pca。(In MATLAB 2019b, the principal function has been changed to PCA function. The functions are the same, and the function name changes. So if you want to use it, remember to change the principal function in the old version of the code to PCA.)
