Properties & Relations (4)
Reverse is its own inverse:
For a matrix m, Reverse[m] reverses the rows:
Reverse[m,2] reverses the columns:
Reverse[m,{1,2}] reverses both rows and columns:
Reverse[expr,n] is equivalent to Map[Reverse,expr,{n-1}]:
Since the default level for Map is {1}, the third argument is unnecessary for n==2:
Reverse[expr,Range[n]] is equivalent to Map[Reverse,expr,{0,n-2}]:
