[Matlab] Plot rectangles with matlab

The script is not really useful. However, it shows how a matlab function works. More matlab functions will be added later.

function PlotRect(Xs,Ys,Xlen,Ylen,LineC,LineS,LineM) % To draw rectangles with given position and properties % Usage: PlotRect(Xs,Ys,Xlen,Ylen,LineC,LineS,LineM) %  e.g., %        PlotRect(0.1,0.13,0.7,0.6,'k','-','.') %        http://scriptdemo.blogspot.com if exist('LineC','var')~=1    LineC='k'; end if exist('LineS','var')~=1    LineS='-'; end if exist('LineM','var')~=1    LineM='none'; end if ~ishold on; hold on; end xx=[Xs Xs+Xlen Xs+Xlen Xs Xs]; yy=[Ys Ys Ys+Ylen Ys+Ylen Ys]; hp=plot(xx,yy); set(hp,'color',LineC,'linestyle',LineS,'Marker',LineM);
