Example:
from sage.misc.citation import get_systems
A=Matrix(RDF,[[1,3,2],[1,4,2],[0,5,2]])
B=vector(RDF,[1,2,3])
get_systems ('A.solve_left(B)')
['numpy', 'scipy']
okay!
but:
get_systems ('A\B')
[]
Why ? we do not use the LU factorization of numpy in the second case?
Other example:
A=Matrix(QQ,[[1,3,2],[1,4,2],[0,5,2]])
B=vector(QQ,[1,2,3])
get_systems ('A.solve_left(B)')
[]
It seems that linbox would be the good tool.
Is it because get_systems do not give the good answer? In that case, how
to make a "trace" of what is really called?
