fun = @(x,y)100*(y-x.^2).^2 + (1-x).^2;
x = linspace(-10,10);
y = linspace(-50,-30);
plot3d(x, y, fun(x,y))

Your function is defined in such a way that you can pass x and y matrices, not just vectors or scalars, into it. Because of that take a look at the MESHGRID function to generate the data points at which you evaluate and plot your function.
