Question

An nXn matrix A has all diagonal elements=0 and non-diagonal elements =1
Find the eigen values of A.

Answer 1

Hartnn asking a question? That's a first :P . Joking ;) .

Answer 2

i know |A-\(\lambda\)I|=0
solving for \(\lambda\) gives eigen values.

Answer 3

for 2X2, its \(\pm 1\)

Answer 4

for nXn, there are n eigen values.
