Awesome!
It would be nice if we could test against that bug fix.

What happens with the new version of M4RI? I gave it a positive review
a few hours ago

Maxima can't do this one either, at least not without some package.

I can't seem to download your test matrix, but are you sure you're not
confusing left kernel and right kernel? What's M *
M.kernel().basis()[0]?

Hi,
I have an integral that is solved by Mathematica, but not by Sage:
integrate( exp(-x^2/2)/sqrt(2*pi) * sign(x-1), x, -oo, oo )
This is actually part of a 3D integral, that mathematica also solves, and
sage has problems with due to the lack of multivariate integration:
integrate sign(x+y)
Dear all,
It works now. I just write as follows:
sage: macaulay2.installPackage('"Schubert2"')
Have fun!

Thanks a lot for the explanations. I like the example of windows or
connections; haven't thought of it from that perspective. It did take
me a long time to figure out what was happening here, so maybe the
above examples would be good in the documentation when the user is
introduced to lists. Not su
