gauss vs gauss jordan

Hi Guys,

I have a simple and basic question....

I know what Gauss elimination is, and what we use it for, and also knows what Gauss Jordan is...what I wanted to know, is when do I use each one ? I mean, in order to solve a system of equations, Gauss is enough, so why do I need Gauss Jordan for ? Why making the extra move of transferring the matrix to a canonical form ?
