draw the surface of the function f(x,y)=e^x+e^y using ezsurf in matlab

main.m
% Define the function
f = @(x,y) exp(x) + exp(y);

% Specify the range of x and y values
x = linspace(-10, 10, 100);
y = linspace(-10, 10, 100);

% Create a meshgrid of x and y values
[X, Y] = meshgrid(x, y);

% Evaluate the function at each point in the meshgrid
Z = f(X, Y);

% Plot the surface
figure;
ezsurf(f, [-10, 10]);

% Add labels and title
xlabel('x');
ylabel('y');
zlabel('f(x, y)');
title('Surface plot of f(x, y) = e^x + e^y');
