- According to me multiplication on matrices are commutative only when
(i) The given matrices are equal
(ii) When the matrices are diagonal matrices and of same order.
(iii) When a suitable identity matrix is being used as prefactor or postfactor
Are there any other possibilities when multiplication of matrices commutative?
2.If there is a matrix A and if assume Am is equal to B then
An∗A=B=A∗An
How is this possible?Is there any proof for it? What logic is being used here?
