So I'm doing my QFT homework, and I need to know what the matrices A and
B would look like if
Tr[A] Tr[B] = Tr[AB]
were true. (For example, it's true if A=B=1 or if A=-B=1). I quickly
walk over to my computer desk, sit down and power up Mathematica. I
enter two matrices and type Trace[A] and got wierd output.
So I go to help and find out Trace is not a matrix operation.
After looking for close to 5 minutes, I've concluded that the Trace
*matrix* operation is either not present or well hidden.
Can someone tell me which one?
Pete
