The code is as follows: function [x, y] = cooline (x1, x2, y1, y2)%cooline integer-coordinate line drawing algorithm.% [X, Y] = Cooline (X1, X2, Y1, Y2) computes an% approximation to the line segment joining (X1, Y1) and% (X2, Y2) with integer coordinates. X1, X2, Y1, and Y2 DX = ABS (X2-X1);DY = ABS (Y2-Y1);% Check for degenerate case.if (dx = = 0) (dy = = 0))x = x1;y = y1;ReturnEndFlip = 0;if (dx >= dy)if (X1 > x2)% always "draw" from left to right.t = x1; x1 = x2; x2 = t;t = y1; y1 = y2; y2
