Try this:

% Plot something.
h = plot(sind(1:1000));
ax = gca % Get handle to current axes object.
xl = xlim(); % Find out x location of the y axis.
% Cover up existing axis with a white line.
line([xl(1), xl(1)], ylim, 'color', 'w', 'LineWidth', 2);
% Draw a dashed line on top of the white line.
line([xl(1), xl(1)], ylim, 'color', 'k', 'LineStyle', '--');
