MATLAB: Using the Classification Learner to train a Multinomial Logistic Regression

Hi,

Currently Classification Learner App has Decision Trees for multi-class classification problems. As you mentioned mnrfit does the Multinomial Logistic Regression, you may use glmfit with corresponding distribution for doing the same. You can find an example here. For more Information you may take a look to the following documentation.
