See also the Wikipedia entry: Gaussian elimination. Nov 11,  · Gaussian elimination using NumPy. GitHub Gist: instantly share code, notes, and snippets. Gaussian elimination with no pivoting. % input: A is an n x n nonsingular matrix % b is an n x 1 vector Gaussian elimination with partial pivoting. % input: A . Motivation Partial Pivoting Scaled Partial Pivoting Gaussian Elimination with Partial Pivoting Meeting a small pivot element The last example shows how difficulties can arise when the pivot element a(k) kk is small relative to the entries a (k) ij, for k ≤ i ≤ n and k ≤ j ≤ n. To avoid this problem, pivoting is performed by selecting.
