My desired output is the figure on the right. The original figure comes from

Here is a kind of messy workaround. Note that this doesn't work if you have the grid on.
h = plot(linspace(-2, 2, 1000), atan(linspace(-2, 2, 1000)));
set(gca, 'XAxisLocation', 'origin', 'YAxisLocation', 'origin');
% draw a white line over the top of the bottom half of the y axis
line([0 0], [0 min(ylim)], 'Color', [1 1 1]);
set(gca, 'Ytick', [0 0.5 1]) % turn off the y ticks at -1 and -0.5
