工作环境( 蓝色粗体字为特别注意内容) 1，软件环境：Windows 7 Ultimate sp1、matlabR2012b 32bit 2，参考文献：① https://jp.mathworks.com/products/statistics.html ② https://blog.csdn.net/zhansama/article/details/82745128 Matlab2012b中使用高斯混合模型报错： gm = fitgmdist(X,2,'Options',options) Undefined function 'fitgmdist' for input arguments of type 'struct'. 了解相关信息，发现fitgmdist函数是Statistics and Machine Learning Toolbox工具箱中的东西，一筹莫展之际，看到了参考文献②，于是将高斯混合模型改为： gm=gmdistribution.fit(X,2,'Covtype','Diagonal','Regularize',1e-10,'Options',options); 顺利执行。来源： https://blog.csdn.net/pang9998/article/details/98755205
