2018-02-15 07:42:23 +0200 | answered a question | trying to plot the phase angle of a Laplace transfer function Thank you that works, the error message is gone... and after a few corrections thats my code: but the output of the second plot is not what i was expecting. Hmmm, sorry I'm not allowed to upload files, but let my explaine. The out put is just a straight line that covers the x-axis and it is supposed to be an s-shaped curve that goes from 0 to -pi/2. So there ist still something wrong with that function arg(). Is there a way to examine the output of the function arg()? |
