Question
Multiplication of real valued square matrices of same dimension is
Options :
not always possible to compute
always positive definite
associative
always positive definite
Answer :
associative
Solution :
Matrix multiplication is associative, which means that for three matrices A, B, and C of appropriate dimensions, (AB)C = A(BC). This property allows us to change the grouping of matrices in a multiplication expression without changing the final result. Hence, this option is correct
