I don't think it's possible to isolate P in this case (unless you don't mind having P**-1 in the result, but SymPy doesn't consider that to be isolated). By the way, is solve() even non-commutative aware? Aaron Meurer On Sun, Sep 2, 2012 at 9:02 PM, Chris Smith wrote: > On Mon, Sep 3, 2012 at 8

[sympy] non-commutative symbols

2012-09-02 Thread Kjetil brinchmann Halvorsen
I want to solve an equation with non-commutative symbols (actually squarematrices): A,P,R = symbols('A P R', commutative=FALSE) Then: solve(R=A*P+P*A,P) but this only gives some involved error? Is this possible? How? Kjetil -- "If you want a picture of the future - imagine a boot stamping o
