2d croos section from a surface

hello,

I want to plot 2d cross section of surface.

for example x = linspace(-1.5,3.5,50); y = linspace(-2,2,25); [xg yg] = meshgrid(x,y); z = exp(-(xg.^2)-(yg.^2)) + 0.5.*exp(-((xg-2).^2)-(yg.^2));

plot(x,y ) for z=.5;

regards

This is usually called a contour plot. You want (only) the z = 0.5 contour.

help contour
