How to obtain the values of parameters of the response distribution in GLM

Say I have a datast called dataset

modelspec = 'Y ~ x1 + x2+ x3 + x4 + x5'; 
mdl_invG = fitglm(dataset, modelspec, 'Distribution', 'inverse gaussian', 'link','log')

Inverse gaussian distribution could be specified by two parameters mu and lamda. Can I get their values when matlab has fitted the model?

Thanks a lot in advance.
