I noticed a strange behavior of the Matlab web command. If I want to open a local html file in the Matlab browser with the command web(full_path_to_file#name_anchor), it fails to open it properly. If I issue the command for the second time and the Matlab web browser is still open, the document is opened at the correct named anchor. I have noticed this kind of behavior in R2016a. Strange undocumented change in the web browser of Matlab or an intentional alteration with some hidden value????
