I would like to plot
f(x,y) = x^2*y/(x^2 + y^2)
How do I do this in matlab?

You need to use the meshgrid (or equivalently, ndgrid) function:
x = linspace(-1, 1);
y = linspace(-2, 2);
[X,Y] = meshgrid(x,y);
f = @(x,y) x.^2.*y./(x.^2 + y.^2);
figure(1)
surf(X,Y,f(X,Y))
grid on
I created a function for ‘f’ here, but you could as easily use it simply as:
f = X.^2.*Y./(X.^2 + Y.^2);
and then plot as:
plot(X,Y,f)
I ‘vectorised’ your code to do element-wise operations. See the documentation on Array vs. Matrix Operations for a full discussion.
