Thread Subject: Plot with step shape

Is there an easy ellegant way to plot(t,x) but with (t1,x1)->(t2,x2) not connected but rather leaving x constant at x1 between t1 and t2, then stepping x to x2, again leaving it constant from t2 to t3 and so on?

thanks in advance for the help

From your description, it sounds like you want the STAIRS function.

Steve, do you know how to plot a impulse graph without using impulse function?

Please try to keep one topic per thread and one thread per topic.

If by impulse you mean the Dirac delta function:

http://en.wikipedia.org/wiki/Dirac_delta_function

one approximation is:

line([-1 0 0 0 1], [0 0 1 0 0]);
set(gca, 'YLim', [-0.5 1.5], 'YTick', [0 1], 'YTickLabel', {'0', 'Inf'})
