Description: Modification of known Gauss method for pivot element elimination that uses internal rows-transposition-vector and works with matrix strictly "col-by-col". The algorithm factorizes the source matrix so that created factor-matrix may be used several times for quick solution of linear systems with many right hand sides.
The main problem for programmers working witn large matrices is how to keep them in computer's memory. Being written in a disk-storage, matrix involves a lot of disk exchanges, because all Matrix-Algorithms use it "row-by-row" and "column-by-column" at the same time. Here we're proposing an original modification of known Gauss method for pivot element elimination that uses internal rows-transposition-vector and works with matrix strictly "col-by-col".
