Hi,
Indeed. Could you please prepare a patch? We'll merge it.
Right. That's why we should allow the user to pass his own simplifying
functions. I think there will always be cases when simplify cannot do
it, so that when the user can pass it's own zero finder, he can fix
that easily. And
Hi Ondrej and Travis,
I have looked through Travis code and compared it to mine. And there
are some differences
in the way the matrices are constructed. And mine is more
heavyweighted with more dependencies.
Here are some features:
* numeric and symbolic solutions
* Pythonic interface for
But there are probably cases where a simplify is not enough. I do not
know
if there is a more robust way of detecting if an expression is zero.
Mathematically speaking, no. But in practise, I am sure it is. Try to
research some literature, and also please create a new issue for each
Hi Ondrej,
Thanks for the help. I dug a little deeper and found that the problem was
that both the LU and GaussElimination solver
could not detect zeros in the pivot elements. The problems disappeared if
the pivot elements were simplified first.
For the GE solver I could just set the simplifed
