annotate scripts/set/setxor.m @ 19974:72ccbd36e23c

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Return a column vector by default for Matlab compatibility (bug #44425, bug #44453). Document that only unique elements are returned from set functions. * NEWS: Announce change in default orientation of return values. * intersect.m, setdiff.m, setxor.m, union.m: Return a column vector by default unless the input is explicitly a row vector. Change docstring to note that only unique, non-duplicative elements are returned.
