I have n points (x ,y coordinates known) of two parallel lines (not perfect straight ) want to draw lines from first boundary points to second boundary with proper slope . Also want to find min & max distance between the lines.

Tried the below code but it draws several lines from min distance point.I want to draw a line (from each POINTS of BOUN2)with proper slope on BOUN1.
if true
% code
end[xy,distance,t_a] = distance2curve(BOUN1,BOUN2,'linear');
plot(BOUN1(:,1),BOUN1(:,2),'k-o',BOUN2(:,1),BOUN2(:,2),'r*')
hold on
plot(xy(:,1),xy(:,2),'g*')
line([BOUN2(:,1),xy(:,1)]',[BOUN2(:,2),xy(:,2)]','color',[0 0 1])
axis equal
if true
% code
end

This code draws straight lines between two boundaries.To find accurate distance between boundaries diagonal coordinates also want to consider.so according to inclination of two boundaries drawn lines must have proper slope. if true % code endBOUN1=reshape(BOUN1',2,[])';
BOUN2=reshape(BOUN2',2,[])';
X1=[BOUN1(:,1),BOUN2(:,1)]';
Y1=[BOUN1(:,2),BOUN2(:,2)]'; line(X1,Y1); axis equal
if true
% code
end
