> Thanks for preparing the spkg, Dima! My problem was probably that I
didn't rebuild ecl first. It works very well now. I think I found the
culprit for the desolve problem:
> so the problem is that we set "domain: complex" and apparently the
behaviour of something there has changed. The assumptions x>0 and y>0
imply that x,y are real (and maxima's assume facility agrees with that),
but as we are well aware, assumptions don't get used everywhere. At the
very least, it seems that assumptions on variables do not affect all the
things that "domain: complex" affects.
Should we provide an option to do "domain: real" on the fly?
I don't know the details of the maxima interface, but I imagine this is
doable...
