Looking at the source for attached_files(), I don't see how removing
elements from the list it returns could detach the files. It looks
like you can detach files manually by deleting from the
sage.misc.preparser.attached dictionary, but there is a function
`detach` that does the job (as

I've just discovered a confidence-shattering bug with numpy matrices.
sage: mymat = numpy.matrix(numpy.arange(6).reshape(3,2))
sage: mymat[:,0]
matrix([[0, 2, 4]])
sage: mymat[:,int(0)]
matrix([[0],

This caused the value of expressions to change when placed inside a

There are some finite element software based on Python - see for
Should conversion from numpy arrays/matrices to lists and sage vectors/
matrices be implemented by a .sage() method on the numpy array/
matrix? This is more consistent with the behaviour interface objects.

whuss at some point added something like this for both Mma and Maple,
though very basic, as part of another ticket (symbolic sums?). I
can't remember where it is and am unfortunately having some internet
issues :( but anyway I believe this code was merged into Sage at some
point.
I'll take this opportunity to point out that the mathematica interface
is somewhat broken at present (i.e. calling .sage() on many
mathematica objects will cause an error, where previously it would
not). Ticket 8495 has a patch awaiting review that fixes this and
extends .sage() to work for many

for the weird orderings here after all - it seems to be sage itself.
For example:

So the Mathematica *input* syntax is closer to the sage *input* syntax,
while the mathematica full form (i.e., the internal tree of operations)

For
FullForm looks like a bit of a headache to me - in part one of the
examples given, InputForm gives Sqrt[5], whereas FullForm gives
Power[5,Rational[-1,2]]. The former is closer to sage's syntax and
should be easier to parse (and a basic parser for InputForm already
exists, in _sage_repr().) So

Now that dsage has been laid to rest, http://sagemath.org/tour-research.html

The doctest failures in
