WebJun 25, 2012 · There are two ways to create a gmdistribution. One is by specifying the mean, covariance, and mixing proportion. The result is a distribution with the parameters you specified. That seems to be what is happening in your case. The resulting objects have the means that you specify. WebSimulate new data from a mixture of Gaussian distributions. Rather than using mvnrnd, you can create a GMM with the true mixture component means and standard deviations using gmdistribution, and then pass the GMM to random to simulate data.
