leads to a PostScript error because you are attempting to take the square root of a negative quantity. It will works over the range 0,pi/2.<br>

Hi all (again...),<br>
one more question.<br>
<br>
I try to plot a part of a superellipse. When I use the code below it works,<br>
<br>
\parametricplot[linecolor=red]{0}{3.141592}{4*(cos(t))^(1.0)|3*(sin(t))^(1.0)}<br>
<br>
but when I change the exponent to something else the 1, e.g.<br>
<br>
\parametricplot[linecolor=red]{0}{3.141592}{4*(cos(t))^(0.5)|3*(sin(t))^(0.5)}<br>
<br>
it does not work. LaTeX runs without error but when I create a pdf with dvipdf<br>
it halts at the figure. Same result if I use \psLame in pst-func.<br>
<br>
If I look at the dvi-file, it does not contain the figure but it does not halt at the figure.<br>
Everything before and after the figure is produced.<br>
<br>
Has anyone a solution to this?<br>
