Return the unique elements common to both a and b sorted in ascending order.
If a and b are both row vectors then return a row vector; Otherwise, return a column vector. The inputs may also be cell arrays of strings.
If the optional input "rows"
is given then return the common rows of
a and b. The inputs must be 2-D matrices to use this option.
If requested, return index vectors ia and ib such that
c = a(ia)
and c = b(ib)
