Partial Pivoting Pivoting (that is row exchanges) can be expressed in terms of matrix multiplication Do pivoting during elimination, but track row exchanges in order to express pivoting with matrix P Let P be all zeros I Place a 1 in column j of row 1 to exchange row 1 and row j I If no row exchanged needed, place a 1 in column 1 of row 1lecture07.pdf
we use to choose which equation to use is called a pivoting strategy The resulting modified algorithm is called Gaussian elimination with partial pivoting 1 5 1 The Algorithm We illustrate this method by means of an example Example 1 x 1 - x 2 + 3x 3 = 13 (1) 4x 1 - 2x 2 + x 3 = 15 or - 3x 1 - x 2 + 4x 3 = 8 or Ax = b where A =1.5.1 LU decompositions with partial pivoting.pdf 2ff7e9595c
