Performing Skewing Computation

Skewing can be realized by wrapping the first column to the right border, then shifting left



• Assume declarations
  region Lop = [1..m,1..n];
  direction right = [0,1];

for i := 2 to m do

[right of Lop] wrap A; --Move col 1 to r border

[i..m,1..n] A := A@right;--Shift last i rows left

end;
