how do i plot level curves in matlab
such as c = 0, 0.5, 1, ..., 3.
i have already computed the code for the function
f (x, y) = (x2 + 3y2)e1−x2 −y2
over the domain −1 ≤ x ≤ 1, −1 ≤ y ≤ 1.

If you want to use a function handle, my code changes to:
f = @(x,y) (x.^2 + 3*y.^2).*exp(1-x.^2-y.^2);
figure
fcontour(f, [-1 1 -1 1], 'LevelList',[0:0.5:3], 'Fill','on')
colormap(turbo)
colorbar
axis('equal')
That is the only change necessary. The 'Fill','on' is optional.
Your code would work with contour or contourf, although not with fcontour, since fcontour creates its own matrices and does not take them as arguments.
