em算法matlab代码-EM_GMM:使用EM算法拟合高斯混合模型的代码

em算法matlab代码EM_GMM Matlab代码使用EM算法拟合高斯混合模型（GMM） 如何使用代码 使用以下方法安装GMM： P = trainGMM(data,numComponents,maxIter,needDiag,printLikelihood) 参数： data - a NxP matrix where the rows are points and the columns are variables. e.g. N 2-D points would have N rows and 2 columns numComponents - the number of gaussian mixture components maxIter - the number of iterations to run expectation-maximization (EM) for fitting the GMMs needDiag - set as 1 if you want diagonal covariance matrices for the components.
