Continuous updating gmm matlab

Try continuously updating weight matrix if possible (sometimes this method can take awhile).

If you can't use continuously updating, also try the iterative procedure, which is just like doing the two-step over and over again until your weight matrix converges over the updates.

No_of_Clusters = 512; No_of_Iterations = 10; [m_ubm1,v_ubm1,w_ubm1]=gaussmix(feature,[], No_of_Iterations, No_of_Clusters); Error using * Inner matrix dimensions must agree.

Error in gaussmix (line 256) pk=px*wt; % pk(k,1) effective number of data points for each mixture (could be zero due to underflow) Do you want use it for Speech processing? He guided me how to use it.( also you need Voicebox too).
