23:50 Slug #875 (In Progress): Interpreter is too slow reading a big polynomial
- I have taken one of Mario's big polys: this one is about 6Mbyte when printed out.
I tried to ways of converting th... -
21:58 Slug #875: Interpreter is too slow reading a big polynomial
- The solution to use @ReadExpr(P, "poly-as-a-string")@ works tolerably well from the point of view of the interpreter,...

Or maybe a fn which takes an idea... -

15:56 Bug #880 (Closed): subst should check that indet is in same ring as 1st arg, but does not.
- @subst@ should check that indet is in same ring as 1st arg, but does not.
Here is an example:... -
15:30 Support #879: LOGAR: make CoCoA-5 easier to use

It simplifies to @a[6]=0@.

I wanted to persuade him to use CoCoA... -
14:51 Feature #877 (In Progress): Easier syntax to make a PRINCIPAL ideal?
- Now I recall what I tried: @ideal(R,x)@ does not work; it says it wants a list instead of a RINGELEM.
Are there an... -
11:43 Feature #877: Easier syntax to make a PRINCIPAL ideal?
- It is already done, both in CoCoA-5 and CoCoALib (in CoCoALib up to 4 generators).
-
11:11 Feature #877 (Closed): Easier syntax to make a PRINCIPAL ideal?
- Currently the way to make a principal ideal is not so natural: the generator must be put into a list.
Are there an... -
11:29 Bug #878: RingElem applied to a symbol (repr as a string)
- Personally I find the situation described quite confusing.
It is not clear to me why @ReadExpr@ is not already inc... -
11:25 Bug #878 (Closed): RingElem applied to a symbol (repr as a string)
- The current design for converting a symbol (repr as a string) into a RINGELEM is inconvenient.
I wanted to do this...
