Trouble with padarray and padarray_algo

The inbuilt function padarray in matlab2015 and 2016 calls padarray_algo(line 66) which seems to be completely undefined. I checked this in several copies of matlab and had the same problem in all of them. This seems like a bug to me. This call to padarray_algo is absent in earlier versions of matlab, before 2015a. Or am I missing something here? Thank you.

>>which -all padarray_algo

If it's not, try

rehash toolboxcache

If that doesn't work, then

restoredefaultpath
rehash toolboxcache
