If it is possible to swap that row with a lower one so that the pivot is not 0, then nothing "happens". If it is not then either of two things can happen:

1) If the corresponding "right side" is 0 then there exist an infinite number of solutions.

2) If the corresponding "right side" is not 0 then there is no solution. - March 5th 2014, 08:31 AMprasumRe: gauss elimination problem
can the case of unique solution be there

if below pivot element which is 0 there comes -1 then do we take the mod for swapping or the actual value
