> N points to be marked)

> Then, do:
> ca=gca();
> cc=ca.children(1).children(1);
> cc.data(:,3)=Zp;  // Be carefull: Zp must be a column-vector
> cc.line_mode='off';
> cc.mark_mode='on';
> cc.mark_style=8; // for diamonds. Run getmark() or see help 
> polyline_properties for other marks
> cc.mark_foreground=color('red');
