Shouldn't this be defined? The return of iterate(enumerate...) is a tuple of an index and t

See this issue sympy/sympy#11044 . That issue was fixed in PR sympy/sympy#11566. Though no test case was added for the lambdify.

What needs to be done?

Add test case that this works just fine:

>>> from sympy import MatrixSymbol, lambdify
>>> x = MatrixSymbol('x', 3, 1)
>>> f = lambdify(x, x.T*x)

Test case needs to

I'm trying out this library for the first time and I'm seeing several places where some shorthand functions would have been really pleasant:

1. Shorthand functions for Pos: Pos::top_right, Pos::bottom_right, Pos::bottom_center etc..
2. Short way to set colors for components. My plots are supposed to be white-on-black, which requires a lot of boilerplate on lots o

If you paste in a t.co link, or whatever, it should follow it.

just to avoid problems some people may have if they haven't ran the format check script before updating localizations.

For the long term, we could clean up the code base a bit by internally using pathlib instead of os.path.join(....) and consorts. This is no vital or overly important task but it will help new contributors, to use it in new contributions and not introduce more old-style code, looking at the rest of the code base.

This is a pretty trivial (but longish) task and is a good first issue for new peo

We either do this all ourselves or do some reordering somewhere, I forget. But we should use the LaTeXML option now! brucemiller/LaTeXML#1044
