Using the matrix capabilities of a graphing utility to find AB
Answer to Problem 43E
Explanation of Solution
Given:
Let consider the following matrix
To find the product of two matrices, it is necessary that the number of columns of first matrix is equal to the number of rows of second matrix. Here A is 3×3 matrix and B is a 3×3 matrix, so the number of columns of A equals the number of rows of B .Thusthe product AB is 3×3 matrix.
Let's use the matrix capabilities of a graphing utility to find AB and for that feed the two matrices and get the product as
