Comment #90 on issue 1598 by mattpap: New polynomials manipulation module http://code.google.com/p/sympy/issues/detail?id=1598 Another update: 1. Added a function for putting polynomials in Horner form. 2. Poly(1) raises GeneratorsNeeded (use Poly(1, strict=False) to get 1). 3. Implemented

Comment #92 on issue 1598 by fredrik.johansson: New polynomials manipulation module http://code.google.com/p/sympy/issues/detail?id=1598 Great progress! Keep up the good work. For complex root isolation, perhaps you can use mpmath to compute approximate roots r_k, then go back to exact

[sympy] Is SymPy project interested in a Dirac notation algebra module

2010-03-16 Thread Asaf Paris Mandoki
A friend of mine developed a python module for doing Dirac notation algebra for quantum computing calculations. I figured this would be a nice addition to sympy and am interested in integrating it. Is this something that would fit with the sympy project? Thanks, Asaf -- You received this

Hi, The website is http://code.google.com/p/openket/ although is outdated. I am attaching the most recent version together with a couple of examples. I guess that we can get rid of most of the code by taking advantage of sympy. I also believe we can improve the API and have a more general
