Why am I getting a solution to a dependent system?
This is a dependent system, but when I solve it I get an answer. Shouldn't I get an error message?
dependent system
A = Matrix([[2,1],[6,3]])
b = vector([1,3])
A\b
ans: (1/2, 0)
Given
b
is in the image ofA
, sob
does have a preimage. Try otherb
such suchvector([1,2])
and you'll get an error.
