Define the variables using syms x y and just plot the function with either of the below functions:

doc ezplot % 2D
doc ezsurf % 3D

Did you try surf()? If not, why not?

x = linspace(-10, 10, 1000);
y = linspace(-10, 10, 1000);
[X, Y] = meshgrid(x, y);
z = X .^ 2 + (Y - (X .^ 3/5)) .^ 2;
surf(x, y, z, 'EdgeColor', 'none')
colorbar
xlabel('x', 'FontSize', 15);
ylabel('y', 'FontSize', 15);
title('z = X ^ 2 + (Y - (X ^ (3/5))) ^ 2', 'FontSize', 15, 'Interpreter', 'none');

and here it is zoomed in to the -1 to +1 range:
