comment decomposing multiplication of two matrices to the sum of rank-1 matrices
You want to decompose the product $DX$ as a sum of rank 1-matrices?

comment Diagonal factorization of upper triangluar matrix to unit uppper triangular matrix
What does unit upper triangular mean? Does it mean that the matrix is upper triangular and every element on the diagonal is 1?

comment Nice Formula for a Function from $\mathbb{N}\cup\{0\}$
So $f(0) = 1$ and $f(1) = 1$? Then it is not a bijection.

You have 1 twice in your set on the left hand set. I guess the first should be zero?

You could try Matrix Computations by Golub and Van Loan (it's a book).

comment How to count algebraic multiplicities to show $\nexists$ an eigenbasis for $A$?
Kind of, but to me, that's a bit strange way of seeing it. Rather, you have only one eigenvector, not three that are equal. But yes, you need three (linearly independent) vectors to span $\mathbb R^3$.

Calculate the eigenvectors and point out that there are too few eigenvectors to form a basis.
