Hi all;
I have this data: x=[ 0, .01 ,.02, .3] ;y=[ 0 ,.01 ,.02 ,.3] ; z=[.08, .06, .02 0 ];
and I want to use it to plot surface then I need to cut it by contoure at z=o;
thanks

I don't understand your data. Shouldn't z be a 4x4 array?

for each (x_i,y_i) I got z_i and I want to label the area where z<0 and the area where z>0 ; for this I thihk that good to use contour.

many thanks
