In terms of Jordan Canonical Form, and more specifically about Jordan Blocks. When there is a definition about Jordan Blocks they say the eigenvalues go on the principle diagonal and the diagonal above it(usually called the super-diagonal) contains the number 1!
I want to understand why there are 1's in the superdiagonal. I have looked all over and no body tries to explain why there is this mysterious 1's in the super-diagonal.
I hope that someone here on this forum can explain this.
