Replying to [comment:13 malb]:
> * `NotImplementedError, "Singular engine in Sage cannot handle matrix
ordering yet."` should be replaced by `NotImplementedError("Matrix term
orderings are not supported by the libSingular interface yet."` or
something along those lines. I propose this change to make it clearer that
Singular can indeed deal with Matrix term orderings and that it is us who
cannot.
I agree.
> * `TypeError: Cannot use a matrix term order as a block.` shouldn't that
be a `NotImplementedError`?
I know Singular allow matrix term orderings in block order. But this
feature is not one of the aims of the current patch. That could be
included in a future patch that use Singular version.
> * I thought the agreement was not to allow 'matrix(0,1,2,3)' but to use
Singular's convention instead? It seems you are allowing at and using it
internally.
I did not agree then. :-) Anyway, I will change it to 'm(...)'
