### LU Factorization

$\left( \begin{array}{ccc} 1 & 2 & 3 \\ 2 & 6 & 10 \\ 3 & 10 & 12 \end{array} \right) = \left( \begin{array}{ccc} 1 & 0 & 0 \\ 2 & 1 & 0 \\ 3 & 2 & 1 \end{array} \right) \cdot \left( \begin{array}{ccc} 1 & 2 & 3 \\ 0 & 2 & 4 \\ 0 & 0 & -5 \end{array} \right)$
or
$A=L.U$ where $A$ is a non-singular matrix and $L,U$ are respectively lower- and upper-triangular matrices.

Every non-singular matrix can be factorized in the product of a lower- and upper-triangular matrix. ( The factorization itself is trivial. )

## Welcome to The Bridge

Mathematics: is it the fabric of MEST?
This is my voyage
My continuous mission
To uncover hidden structures
To create new theorems and proofs
To boldly go where no man has gone before

(Raumpatrouille – Die phantastischen Abenteuer des Raumschiffes Orion, colloquially aka Raumpatrouille Orion was the first German science fiction television series. Its seven episodes were broadcast by ARD beginning September 17, 1966. The series has since acquired cult status in Germany. Broadcast six years before Star Trek first aired in West Germany (in 1972), it became a huge success.)
