It's easy to flip along a dim using `end:-1:1`. So why design the builtin fliplr, flipud functions?

YMMV
  • higher level; easier to read and remember
  • fliplr is faster for large vectors (R2018a)

  • Works long any arbitrary dimensional array:
x = rand(3,3,3,3,3);
flipud(x)
Though flip() is now the preferred means.
  • Easier for users not fluent in indexing.
