PCA1
The important method is [COEFF,SCORE] = princomp(x) which takes in your data “x” and stores its projection into PCA space in “SCORE” which I then output to csv. I still need to find out how to project back into normal space but I think it should be just as straightforward as this was. For more info on “princomp” type “help princomp” into matlab and have a look at the help files.

signaltoolbox-0.2
matlab时频分析工具箱时频分析工具箱time-frequency analysis toolbox 第二代，比第一代增加了许多信号处理的函数，有些函数进行了功能的增进。使用的时候，解压到MATLAB安装目录的toolbox目录下，并在matlab中将其添加到搜索路径中使用。(time-frequency analysis toolbox matlab second generation than the first generation adds many signal processing functions, some functions have been enhancing features. Use it, extract it to MATLAB installation directory toolbox directory and search paths to work.)
