Concept explainers
To state: that whether the matrices are of proper dimension to perform the operation
Answer to Problem 107E
the operation
Explanation of Solution
the operation
Given information :
The dimension of matrices
by the definition of subtraction matrices the order of both matrices must be same.
Since to perform the operation
Here the order of matrices
The dimension of the resultant of the operation
by the definition of multiplication matrices the number of columns of first matrices must be the same with the number of rows of second matrices.
Since to perform the operation
Here the order of matrices
Thus, the operation
The dimension of the resultant of the operation
