%DRAW   Draw alpha,r-line feature.%   DRAW(L,IDS,COLOR) draws the alpha,r-line feature L into%   the current figure with color COLOR. Enable and disable%   display of feature identifiers with the flag IDS being%   1 or 0. COLOR is a [r g b]-vector or a Matlab color%   string such as 'r' or 'g'.% %   H = DRAW(...) returns a column vector of handles to the%   line objects of the drawing.%%   See also ARLINEFEATURE.% v.1.0, Dec. 2003, Kai Arras, CAS-KTHfunction h = draw(l,ids,color);% ConstantsFSIZE = 0.1;           % font scale in [m]FOFFS = 0.03;          % font offset in [m]MUE   = 100;           % infinite-line draw coefficient% Get valuesal = l.x(1);rl = l.x(2);% Draw labelif ids,  x = rl*cos(al);  y = rl*sin(al);  theta = al + pi/2;  h1 = drawlabel([x y theta],num2str(get(l,'id')),FSIZE,FOFFS,color);end;% Draw infinite linex1 = rl*cos(al) - MUE*sin(al);y1 = rl*sin(al) + MUE*cos(al);x2 = rl*cos(al) + MUE*sin(al);y2 = rl*sin(al) - MUE*cos(al);h2 = plot([x1 x2],[y1 y2],'Color',color);h = cat(1,h1,h2);
