Regarding the switch in 2012a :
Other Functionality Being Removed or Changed
Functionality: isequalwithequalnans What Happens When You Use This Functionality: Still Runs Use This Instead: isequaln Compatibility Considerations: Replace all instances of isequalwithequalnans with isequaln.
Comments [2,3] have suggested that the reason for the switch is just to shorten the name of the function. Is this the true change, or is there any other benefit (performance) to consider in the new function?
Thanks for your comments.
