Matlab marker size color

plot(xini(1),xini(2),'ko','MarkerSize',10, 'MarkerFaceColor',[0,0,0])

plot(tgt(1),tgt(2),'rd','MarkerSize',10, 'MarkerFaceColor',[1,0,0])

Skip items in Matlab legend

You can specify a vector of plot handles to use in the legend. For example:

h1 = plot(rand(1,10));      % Blue line
hold on;
h2 = plot(rand(1,10),'r');  % Red line
h3 = plot(rand(1,10),'g');  % Green line
legend([h1 h3],{'hello','world'});  % Only the blue and green lines appear
                                    %   in the legend
