how to mark 2D plot with shapes for long array?

trying to mark 2D plots with shapes using the following command:

h=semilogy(lambda,Hb);
set(h,'linestyle','-','color','b','marker','s')

a problem occure when the plots are for large array of vectors, then the shapes are crammed up and i cant really distinguish from them.

what can i do?

Use the 'markerindices' argument, introduced in 2016b

plot(x, y, 'markerindices', [1:10:lenght(x)])

puts markers on every 10th point. In older released you need to use something like

 plot(x, y, 'k-',...
 x(1:10:end),y(1:10:end),'ko')

Which is really annoying as you get 2 different line objects.
