The product
Answer to Problem 91E
The product matrix is given below as,
Explanation of Solution
Given information:
The matrix is given below as,
Formula used:
Matrix multiplication is used.
Calculation:
To find general rule for diagonal matrix, first we take different example of multiplication of diagonal matrix.
First we take
Now multiply AB matrix
Now take another diagonal matrix of different dimension
Multiply both matrixes AB
Now we take a general diagonal matrix A and B
Multiply matrix A and B
Above example show that on multiplying two diagonal matrix of same size, perform multiplication of the diagonal element without using row to column multiplication. The product of that matrix in general gives the product matrix in following way.
Conclusion:
The product matrix is given below as,
