In 371 BC, an outmanned army faced certain defeat at the hands of the Spartans. Refusing to surrender they employed a new formation in a final effort to save their city. By staggering their troops diagonally, each unit behind and to the right, they toppled the mighty Spartan army and invented the echelon, a military formation that is still used today. In the same spirit of innovation, Springfield Armory introduces the Echelon, a superior approach to modern pistol design.
$$\beginbmatrix1 & 2 & 3\\2 & 3 & 4\\-1 & 0 & 2\endbmatrix$$in row echelon form:$$\beginbmatrix1 & 2 & 3\\0 & 1 & 2\\0 & 0 & 1\endbmatrix$$I am aware that I can do a sequence of elementary row operations.
