Is there any way to force
Det to do itself in a certain way?
I've been running the same notebook on 2 differents computer, one MacOSX Lion and one W7 (both 32bit) with Mathematica 188.8.131.52 on the two of them, and we don't get the same
Det expression and
Solve[Det[F[x]]==0,x] doesn't give the same solutions either.
How to know which one says the truth? How could we calculate the
Det in order the have the same solutions on both computers?
Note: as its the same nb the matrices (26*26) are exactly the same.
