I have this two matrices

uA := Matrix([[-w^2+x^2+y^2-z^2, -2*(w*y+x*z), 2*(-w*x+y*z)], [2*(-w*y+x*z), w^2+x^2-y^2-z^2, -2*(w*z+x*y)], [2*(w*x+y*z), 2*(-w*z+x*y), -w^2+x^2-y^2+z^2]])

and

 

UA := eval(uA, {w = -w, x = -x, y = -y, z = -z})

 

and I want to check that their are the same. I have tried

evalb(uA = UA)

 

but it says it false. It should say that is true, because - I think- this two matrices are the same.

Does anyone know what is wrong?

 

Many thanks
