MATLAB: Problem with simple “flip” function

Question

I try this simple exemple of flip function

Flip Column Vector A = [1;2;3]; B = flip(A) B =

     3
     2
     1

and I get this error in lieu on B=…. !?

Undefined function 'flip' for input arguments of type 'double'.

I use R2013a

Answer 1

The function isn't flip; they're separate functions fliplr and flipud for row/column vectors in particular.
