Some question in the document：pmtk3/toolbox/SupervisedModels/logreg/logregFit.m 

In the line 12 the author defines the three default values of regType：“ % regType       ... 'L1' or 'L2' or 'none'”，but  when solving optimization problems from the line 133 to the line 141，there are only the item 'L1' and 'L2'，how can I got the posterior distribution of the parameter W without the regularization terms？Has anyone studied this question? thanks a lot！！！
