If Aland B are 5 X 9l matrices and Cl is a 7 X 5l matrix whi

If Aland B| are 5 X 9l matrices, and Cl is a 7 X 5l matrix, which of the following are defined?

Solution

A) A - B is defined since order of A and B is same

B) C^T is defined and it\'s order is 5 X 7

C) AB^T is defined since the number of columns of A are equal to number of rows of B^T

D) C - B is not defined since the order of C and B is not equal

E) BA is not defined since the number of columns of A are not equal to number of rows of B

F) CA is defined since the number of columns of C are equal to number of rows of A
