%% Specify Plotting Ranges % Plot the symbolic expression |x^2 + y^2| over the range % |-1 < x < 1|. Because you do not specify the range for the |y|-axis, % |ezsurf| chooses it automatically. % Copyright 2015 The MathWorks, Inc. syms x y ezsurf(x^2 + y^2, [-1, 1]) %% % Specify the range for both axes. ezsurf(x^2 + y^2, [-1, 1, -0.5, 1.5])
