Thanks Aaron,
I'm sorry for that. In my previous GSoC project I used mercurial and
http://codereview.appspot.com/ and I never tried github before :(
I've read doc about workflow and created pull request

Maybe https://github.com/sympy/sympy/wiki/Git-hg-rosetta-stone will be

Don't worry if you don't know git. We expect that incoming students
won't. We will teach you everything that you need to know. Making

Hi,
The new plotting module tests keep a number of reference png images
for comparison. ~20 images each ~200KB is more than the size of our
code base. I do not know it it will be a good decision to burden git
with those. What do you think?

I just did a git clone, and everything, including the checkout is 52MB.
Is it possible to use SVG versions of the images? That should be much
smaller, I would think, as the plots are vector images anyway. Also,
git will handle any diffs on a SVG much better than from a binary
file.

I don't think it's possible to convert a code closure into a symbolic
object. Once the lambda is created, we can't know what it does (unless
you try to parse the bytecode).
We should be able to sympify the string form of a lambda, but it
presently doesn't work. I thought we had an issue for this,
I'm assuming you answered your own questions here with your symbolic

Just one issue: the sympification of lambda x : x

I think int(sin(2)) should work. It should give the same thing as
int(sin(2).evalf()). Is there an open issue for this? If not, please

Is there an intermediate format in matplotlib to which we can compare? It
seems odd to compare images that are generated by an external library.
Couldn't a change in matplotlib cause our tests to fail?

So, I'm trying to get into the most basic use of sympy for a nested

attempting to get it to solve a 3 dimensional distance equation for
one formula. Here's how it goes:

I was thinking this as well. Though it might not just be for tests (e.g.,
examples as well). That's why I asked what they are used for.

I am not aware of any matplotlib internal representation that can be
used. Moreover I was left with the impression that comparison of final
images is exactly what the matplotlib team does in their unittests.
The ipython notebook also uses final images (png or svg). The same
goes for matplotlib's ex
For examples, we could investigate a solution that involves generating
them when we release.

How about testing exactly what is passed to matplotlib? That would
also generalize to other backends, and would use virtually no space.
It would also be independent of matplotlib itself (we don't really wan
to test their functionality, as there's little we can do about it).

OK, I will redo the tests. For the moment no images will be generated.
Also at least for the moment I will leave the comparison code in, but
commented out. It can be deleted later if we decide firmly against it.
The comparison code was verified to work on another machine by @miham.

Yeah, I did kind of mess that one up. I want it to be less than 2.
I'm trying to solve for x and y, so I expect it to produce a line
rather than a single variable answer. a is an actual number, so
that's 'hard coded' in to the equation, rather than being another
symbol.
If those two were the onl
Can you print your origin and destination variables? When using the
following, I don't have any problem:

(a, b, c, x, y, z)

>>> solve(eq, x)
[a - sqrt(-b**2 + 2*b - c**2 + 2*c*z - z**2 + 3), a + sqrt(-b**2 + 2*b - c**2 +
2*c*z -

var() is the same as symbols(), except you don't have to write the
"=". The way it works is kind if hackish (it injects the variable
names into the namespace) so you should only use it interactively
(i.e., when typing commands at the Python prompt). If you are using a
script, you should use symbols
