MATLAB: How to show the contour plot of two functions in a graph

See if this does what you want:

x = linspace(-10,10);
y = linspace(-10,10);
[X,Y] = meshgrid(x,y);
Z = X.^2+Y.^2;
figure
contour(X,Y,Z, 'ShowText','on')
Z = X +Y;
hold on
contour(X,Y,Z, 'ShowText','on')
hold off

Use the hold function to make multiple plots on one set of axes.

Try this:

[X,Y] = meshgrid(linspace(0, 10, 25));
Z = 5*X.*Y.*(1-X-Y);
figure(1)
surf(X, Y, Z)
grid on
