Recall that the process ofGaussian eliminationinvolves subtracting rows to turn a matrix A into an upper triangular matrix U. WebGAUSS ELIMINATION WITH PIVOTING…. In the basic gauss elimination method, the element a ij when i=j is known as a pivot element. Each row is normalised by dividing the coeffients of that row by its pivot element. That is, a kj = j=1, …., n. If a kk =0, k th row cannot be normalised. Therefore, the procedure fails.
