Thank you Hannes.
Your link http://surfex.algebraicsurface.net/view ... nuitem=160
doen't work for me, and I get a 404 error.
I searched for surf.exe in the Singular folders of my existing installation and indeed found it in
the cygwin-->bin folder. The surf.exe which I have has a size of 457KB and I am using Singular version 4.0.2 released in February 2015.
When I try to run the plot example, that is given in the online manual here https://www.singular.uni-kl.de/Manual/l ... tm#SEC1816
I get the following error:
> LIB "surf.lib";
ring rr0 = 0,(x1,x2),dp;
ideal I = x1^3 - x2^2;
plot(I);// ** loaded /usr/bin/../share/singular/LIB/surf.lib (18.104.22.168,Jun_2013)
> // --------- plane curves ------------
. ring rr0 = 0,(x1,x2),dp;
> ideal I = x1^3 - x2^2;
Close window to exit from `singularsurf`.
? calling `surf` failed
(The shell returned the error code 256.
? leaving surf.lib::plot
Any idea what went wrong, please?
