SameTest
is an option whose setting gives a pairwise comparison function to determine whether expressions should be considered the same.
Details
- SameTest->f specifies that f[e1,e2] should be evaluated whenever it is necessary to determine whether pairs of expressions e1, e2 should be considered the same.

Intersection considering comparison modulo 3:
This matrix is antihermitian for a positive real 
, but AntihermitianMatrixQ gives False:
Use the option SameTest:
This matrix is symmetric for a positive real 
, but SymmetricMatrixQ gives False:
