Dear Oscar, Thanks! I installed it (I used anaconda, rather than pip), all went well. As you predicted, I did not find any difference so far, will keep on observing.

It is very easy to install gmpy2 (pip install gmpy2) to see if it does speed anything up. I don't think that the mechanics module explicitly uses any of the low-level polynomial code so the question would be whether something like cancel or factor is being used somewhere. My expectation is that things like that would be avoided in mechanics. The next post will talk about matrices which is more relevant for the mechanics module although the matrices would be matrices of polynomials so having fast polynomials also makes a big difference to linear algebra. This would be very relevant to our previous discussion here: https://github.com/sympy/sympy/issues/24679 -- Oscar -- You received this message because you are subscribed to the Google Groups "sympy" group.
