Hello, how can i show the contour values on the plot?

f = @(x1,x2) exp(-0.05*x1)*sin(x1)+exp(-0.05*x2)*cos(x2);

fcontour(f,[-10 10 -10 10])

colorbar

The fcontour function does not have a 'ShowText' property, so overplot it with a normal contour plot and set 'ShowText','on' to show the levels.

f = @(x1,x2) exp(-0.05*x1).*sin(x1)+exp(-0.05*x2).*cos(x2);

figure

hfc = fcontour(f,[-10 10 -10 10]);

Xm = hfc.XData;

Ym = hfc.YData;

Zm = hfc.ZData;

hold on

contour(Xm,Ym,Zm, 'ShowText','on')

hold off

colormap(turbo)

colorbar
