Suppose I have following polynomial:
poly= Poly(6*x**4*y**5 + 3*x*y**2,y,x)
It's dictionary is
poly.as_dict() # {(5, 4): 6, (2, 1): 3}
How can I restore poly from dict?
How do I know that (5, 4) - > (y, x) ?
poly.free_symbols is set, so it is unordered.
Is there any way to fetch that from Poly?
One way I think is following:
variables = [x,y]
poly= Poly(6*x**4*y**5 + 3*x*y**2,variables)
#(5, 4) - > variables
And next question: how are coeffcients are ordered? Can I change order?
order keyword throws exception...
