Hey guys, I've been having trouble with this matrix problem for a while now.
Here it is:
M =
Find all 2 x 2 matrices A = where (1,2) = (2,1) entry such that AM = -MA
I've tried matrix multiplication for both AM and -MA and tried equating appropriate values but I end up with a zero matrix. I also tried multiplying both sides by A inverse, but again I get a zero matrix. Any help is appreciated, thanks.
