How can I show only a part of the yaxis (i.e. from zero to infinity), as shown in the right figure, here below?
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
