Hi,
Guys can somebody explain for me the code of the following
\SpecialCoor
\begin{pspicture}(-6,-6)(6,6)
\psaxes{<->}(0,0)(-6,-6)(6,6)
\psset{arrows=->}
\multido{\ia=-5+1}{11}{%
\multido{\ib=-5+1}{11}{%
\pstVerb{/x \ia\space def
/y \ib\space def
y 0 eq
{/ValueTempA 0 def
/ValueTempB 0.5 def}
{/ValueTempZ 2 1 x x mul y y mul div add sqrt mul def
/ValueTempA 1 ValueTempZ div def
/ValueTempB x y ValueTempZ mul div def}
ifelse}
\psline(! x ValueTempA sub y ValueTempB sub)
(! x ValueTempA add y ValueTempB add)}}
\end{pspicture}
Because when I tried to imitate the above code for the vector fields
function <2x,y> I got something different.
Thanks
