- I have made @inverse@ interruptible (@DetByGauss@). I suppose we should also make a @DetByCRT@ at some point?
-
12:05 CoCoALib Feature #718: Insert calls to CheckForInterrupt
- Make matrix *@inverse@* interruptible (at least for matrices over @ZZ@).

- Thanks Nico for the bug report.
I wonder why that face is even defined? When, if ever, is it used?

12:23 CoCoALib Slug #1756: deg(f) is slow if f is long
- We could have, instead of *IsStdGraded* a function *IsStdGradedCompatible*, better for an ordering.

No doubt the problem is that it tak... -
18:54 CoCoALib Slug #1756: deg(f) is slow if f is long
- What do we want to do if the OrdMat has a first row being all the same but not equal to 1?
The grading is StdDeg com... -
18:38 CoCoALib Slug #1756 (In Progress): deg(f) is slow if f is long
- I think I have mostly solved this issue now. Anna had already added a *@IsStdGraded@* function in 2013. I have modi...

17:10 CoCoALib Bug #1758: Graeffe "sign bug"
- A reasonable solution could be to define @GraeffeN(f,n)@ to be the same as @resultant(f(y), y-x^n)@.
This would then... -

- In comment 1 I used *@EmptyList@*; in comment 2 I used *@NoGens@*
I think I dislike @EmptyList@ because it is rather... -
