(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Give an example of an operator whose matrix with respect to some basis contains only 0's on the diagonal, but the operator is invertible.

3. The attempt at a solution

I think the operator will not have an upper-triangular matrix since it would then not be invertible.
