| Post subject: | Ring Parameters |
I am writing a library and I need to use parameters in a function, but I can't just define a new ring with the parameters. I need to add the parameters to the basering that I'm working with. I want to know if there is a function that can do this to me, like the function 'extendring', that adds new variables to the ring. Thanks any help. |

There is no procedure which automatically adds a paramater, but it is easy to write one via the ringlist command: convert the ring into a list list L=ringlist(r); modilfy the first entry and create a ring from the changed list: def r_with_paramater=ring(L); The help to ringlist gives examples: http://www.singular.uni-kl.de/Manual/3-0-1/sing_274.htm |
