Hi,
Should we deprecate "ln"? NumPy doesn't have any "ln", neither does
Python's math library. Everybody uses "log". In sympy,
we just have "ln = log" anyway, so I am all for starting to return a
deprecated warning if people use it. And remove it eventually in later
releases.

Cool. Does your university use SymPy, or is it just something that
you personally use?
And by the way, even if you're not from a developing country, you can
save a lot of money by using open source software (assuming it is of
comparable quality).

Yes, the "general expressions" meant Expr objects. But I think you
should allow more advanced fields than just QQ like the coefficient
fields in the Polys, things like ZZ(x), or even ZZ (if you
reuse code from the polys, it should be easy to do anything that the

By 'rational function terms' and'general expression terms' do you mean
that a matrix should take Expr objects as elements ?
Of course, I missed to add it in the list of groundtypes. Felt it was
obvious.

I think a Matrix could also have, for example, rational function

Functions of this layer will receive the Matrix data as arguments.

There was a discussion over at

Real class to Float, because the name fits the class better. The
reasoning is that Real represents floating point numbers, not any real

As for how to do it, can sympify be extended to parse any python
