ezsurf z2=x2+y2 in matlab

To plot a surface defined by the equation z2 = x2 + y2 in MATLAB using ezsurf function, follow these steps:

1. Define the function as an expression:

main.m
f = 'x.^2 + y.^2';
19 chars
2 lines

2. Use the ezsurf function to plot the surface:

main.m
ezsurf(f);
11 chars
2 lines

The complete code would look like this:

main.m
f = 'x.^2 + y.^2';
ezsurf(f);
xlabel('x');
ylabel('y');
zlabel('z');
title('Surface Plot of z2 = x2 + y2');
108 chars
7 lines

This will produce a 3D surface plot of the equation z2 = x2 + y2. The xlabel, ylabel, zlabel, and title functions set the labels and title of the plot.
