Matrix elimination
Posted:

Dear comunity, I'm trying to play around with the simple matrixes in Mathematica for the first time and I have beginners question:
Does Mathematica have a function, which makes the intermediate step of Gaussian elimination to produce just eliminated upper triangular matrix? Function UpperTriangular only cuts the lower triangular places off (which is not what I need) and RowReduce makes the completely reduced echelon form of matrix. I needed the step in the middle of the RowReduce way.
Thanks in advance for any tips
Jakub
