- 12:18 Bug #1758: Graeffe "sign bug"
- I have removed the "sign tricks". Also checked-in.
I wonder if the doc should be changed to point out that sometime... - 11:27 Support #1761: MakeTermOrdMat: improve error mesg
- Source code is in @MatrixForOrdering.C@
I do wonder if the call to @MakeNonNeg@ is safe: why is the loop on line 133... - 11:25 Support #1761 (Closed): MakeTermOrdMat: improve error mesg
- The fn @MakeTermOrdMat@ should give a better error mesg if the input matrix is not non-negative:...

- 11:08 Slug #1756: deg(f) is slow if f is long
- Lex is clearly not std deg compatible, but if the LPP contains only the last indet, we could short-cut. Not sure thi...
- 11:04 Slug #1756: deg(f) is slow if f is long
- Is this an easy task which we could quickly resolve?
Do we have a test case?...

- 22:15 Bug #1758 (In Progress): Graeffe "sign bug"
- Currently, trying to compute @graeffe(f)@ over a finite field produces:...
- 22:10 Bug #1758 (Closed): Graeffe "sign bug"
- I put in a (not-so) "clever trick" in @graeffe@ and @graeffe3@ so that the LC is positive if the coeff rings is @ZZ/Q...
- 13:52 Feature #1755: CheckForInterrupt: give more info?
- Create an example of using *@GetAndResetSignalReceived@*

- 19:31 Slug #1754: IsSqFree poorly implemented
- I have improved the code. It is also a bit faster (than 0.99818).
Will check in soon.

- 18:04 Slug #1757: gcd(f,f) is slow
- Here is just 1 example illustrating the point:...
- 18:03 Slug #1757 (New): gcd(f,f) is slow
- Consider making a special case of @gcd(f,f)@ or indeed @gcd(f,k*f)@ where @k@ is a scalar.
- 18:01 Slug #1754 (In Progress): IsSqFree poorly implemented
- Source code around @NumTheory-factor.C:690@

- 09:32 Slug #1756: deg(f) is slow if f is long
- Oddly, i believed I had recently sorted this out... evidently not.
We need a function to say whether the ordering on... - 09:29 Slug #1756 (In Progress): deg(f) is slow if f is long
- In a poly ring with a std deg compatible order we can compute @deg(f)@ just by looking at the first PP.
It seems we ...
