WebFeb 19, 2024 · MATLAB functions use Sigma in Multivariate Normal, and this is covariance matrix. The gmdistribution class uses Sigma for covariance matrix. So if you extract the diagonal elements out of that, you have variances. But pdf uses sigma, i.e., standard deviation. Note:You'll have to check whether gmsigma (2) gives you the (1,2) element of ...
