From: mona on 22 Dec 2009 12:21 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

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 mona
