- 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 $A^m$ is equal to B then
$A^n*A=B=A*A^n$ How is this possible?Is there any proof for it? What logic is being used here?
