If A is an m × n matrix on which wewant to do an elementary operation, then there is amatrix E such that EA is the new matrix after theoperation. Such an E is called an elementary matrix.This idea can be helpful, for instance, in the designof algorithms. (Computationally, it is generally prefer-able to do row operations directly, rather than bymultiplication by E.)E₁(a) Show that the following are elementary matrices,for interchanging Rows 2 and 3, for adding −5 timesthe first row to the third, and for multiplying the fourthrow by 8.E2E3=10 00 00 101=-5 0 100 011 0 0 001 001000 000 0 0 110 0 004P₁ P₂ + 4,0 00 1 0000 8
