121. How to reverse an array or character string#
topic: Arrays
Note
This tip is a draft1.
Write
v = v(size(v):1:-1)
to reverse a 1-D array v with lower bound 1, otherwise
v = v(ubound(v):lbound(v):-1)
v(::-1) is a zero-size array unless size(v) = 1. A character string can be reversed with the function shown.
