fitgmdist with hyper-parameters

Hi, Is there a function in MATLAB to fit a Gaussian mixture model with hyper-parameters for mean (Normal distribution with mu_0 and sigma_0) and variance (inverse Gamma with a0 and b0)? I did not find an option for hyper-parameters in the 'fitgmdist' function, curious to know if there is any other function.

Thanks, Sharmi
