### Diagonalization: Eigenvalues Vs Elementary Row Operations [duplicate]

Using elementary row operations, a matrix A $\in \mathrm{R}^{n \times n}$ can be reduced to a Row-Reduced Echelon (RRE) form. Using the RRE form of A, the bases of Nullspace and Range can be obtained....

### Why are Eigenvalues So Important? [duplicate]

I understand the definition of eigenvalues and eigenvectors. Eigenvectors just stretch when applied by a linear transformation (a matrix). So far so good. I am surprised by the amount of times they ...
