Hi all,
I have
[xx,yy]=meshgrid(x,y)
zz=f(xx,yy)
and I plot zz with
contour(xx,yy,zz)
now I would like to plot some lines on this plot something like and/or some
points
I tried (with hold on)
plot3(0,0,500,"r+");
and
plot(0,0,"r+")
but I got only "Notice: cannot contour non grid data!"
how can I do?
thanks
Claudio
