WebCreate a gmdistribution object by using the gmdistribution function. By default, the function creates an equal proportion mixture. gm = gmdistribution (mu,sigma) gm = Gaussian mixture distribution with 2 components in 2 dimensions Component 1: Mixing proportion: 0.500000 Mean: 1 2 Component 2: Mixing proportion: 0.500000 Mean: -3 -5 WebCluster Data. Generate random variates that follow a mixture of two bivariate Gaussian distributions by using the mvnrnd function. Fit a Gaussian mixture model (GMM) to the generated data by using the fitgmdist function. Then, use the cluster function to partition the data into two clusters determined by the fitted GMM components.
