WebTo come up with your own idempotent matrix, start by choosing any value of a. For an example, let’s choose 3. Make d = 1 – a, or -2. Now -2 = bc + 4, by our a last equation above, so -6 = bc. As a quick check, see that this fits our first equation, a = 3 = a 2 + bc = 9 – 6. We can choose any values of b and c that fit bc = -6, so to make ...
