10:54 Design #1467 (In Progress): Change syntax apply(phi,M) into phi(M)?
We could permit both syntaxes, perhaps making *@apply(...)@* obsolescent?
[JAA does not much like having two differe...

10:44 Design #1467: Change syntax apply(phi,M) into phi(M)?
I noticed this while making a prototype impl for automatic ringelem promotion. In particular for ringelem times matr... John Abbott
10:39 Design #1467 (Closed): Change syntax apply(phi,M) into phi(M)?
Currently to apply a RingHom to the entries of a matrix or a C++ vector we must use the fn *@apply@*.
Is it better...
John Abbott
10:34 Feature #1150: New fn: transform ideal with ring hom
What is this supposed to mean? Does it mean the ideal generated by @{phi(f) | f in I}@? What else could it mean?
W...

10:26 Feature #1466 (In Progress): Ops += *= etc for Matrices?
It is not _necessary_ to make these operators, but anyone used to C++ might expect them to work.
I suggest:
* mak...

11:11 Feature #1466 (Closed): Ops += *= etc for Matrices?
Should we make "assign-op" operators for matrices?

21:42 Design #1465 (In Progress): mul(MAT,MAT,MAT)
I have commented out the fn, and modified *@power(MAT,n)@*.
Everything compiles and runs fine.
I suggest eliminat...
John Abbott
21:40 Design #1465 (In Progress): mul(MAT,MAT,MAT)
There is a fn *@mul(MAT,MAT,MAT)@*
Is it any use?
The impl is exception-safe, so internally it creates a new mat,...

20:27 Design #1462: Change CoCoA_ERROR into CoCoA_THROW_ERROR
I have removed the macro *@CoCoA_THROW@* for the following reasons:
* a macro is an ugly implementation trick
* it ...
John Abbott
09:41 Design #1464 (New): What is the difference between InterruptReceived and InterruptedBySignal
It seems to be superfluous to have both *@InterruptReceived@* and *@InterruptedBySignal@*.
Review the design/impl; a...

21:02 Design #1462 (Feedback): Change CoCoA_ERROR into CoCoA_THROW_ERROR
I have updated doc too. Also checked that everything works with debugging active.
John Abbott
20:08 Design #1462: Change CoCoA_ERROR into CoCoA_THROW_ERROR
I have changed all calls to @CoCoA_ERROR@ into @CoCoA_THROW_ERROR@; I do think the code is a bit more readable with @... John Abbott
20:19 Design #1463 (In Progress): SmoothFactor: use FactorMultiplicity
The current implementation of @FactorMultiplicity@ makes it hard to use inside @SmoothFactor@ (because it returns onl... John Abbott

20:03 Design #1462 (In Progress): Change CoCoA_ERROR into CoCoA_THROW_ERROR
I have started. Defined the new macros @CoCoA_THROW_ERROR@ (drop in replacement for current @CoCoA_ERROR@).
Also de...
John Abbott
16:55 Design #1462 (Closed): Change CoCoA_ERROR into CoCoA_THROW_ERROR
I suggest changing name of the macro to *@CoCoA_THROW_ERROR@* so that it i obvious to the reader that the error objec... John Abbott
20:01 Feature #1457 (Feedback): Make SmoothFactor interruptible
Speed test was OK. Also improved impl of @SmoothFactor@, but see #1463.
Checked in.
John Abbott
16:29 Feature #1457 (Resolved): Make SmoothFactor interruptible
The problem is that @SmoothFactor@ has two (nested) loops either of which can be slow; but I had inserted a call to @... John Abbott
19:56 Design #1463 (Closed): SmoothFactor: use FactorMultiplicity
@SmoothFactor@ contains almost a duplicate implementation of @FactorMultiplicity@.
Tidy up: Make @SmoothFactor@ ca...
John Abbott
19:54 Slug #1170: SmoothFactor: slow when a factor is found
The given example is no longer slow.
The trick of testing for primality is used only when @RemainingFactor@ is not t...

16:45 Bug #1458 (Rejected): Redesign interrupt mechanism?
What I wrote in comment 5 was perhaps once correct, but not any longer.
This bug did not exist where I thought it ex...

09:32 Design #1460: Name of TensorMat; change to KroneckerProd?
Another matter is *where* to put the defn of the function.
Currently @TensorMat@ is defined in @MatrixSpecial.C@; I ...
