I'm migrating existing Matlab code that used to run in R2011a to a newer version R2015b. There's a situation with the Set functions intersect, ismember, setdiff, setxor, union, and unique. According to the Matlab release notes these functions changed their behavior in R2012a and in order to maintain their legacy behavior I need to add a legacy flag to the function call (e.g. ismember(a,b,'legacy'). My existing code has thousands of calls to the Set functions so doing this manually is starting to look as a very difficult task to do and very prompt to human error.
Did Mathworks create some kind of tool to support users migrate old code but maintain their legacy behavior? In other works, is there an automated way, supported by Mathworks, to attach this legacy flag to the set functions?
