4. a. Find the diagonal entries of AB by inspection.
b. Find a diagonal matrix A, given
Hint
Mathematicsb) Diagonal matrix is that matrix that has zero free elements only in the diagonal which runs to the lower right from the upper left based on mathematics, which differs from algebraic definition. Multiplication of diagonal matrices is always cummulative. It's also referred to as scaling matrix since multiplication of matrices with it leads to adjustments of scale....
