In this question, we use Gaussian elimination to solve a system of linear equations using partial pivoting and backwards substitution.TimeStamp !-----...
This requires searching in the partial column below the pivot element. Partial pivoting is usually sufficient. T. Gambill (UIUC). CS 357. February ?, 2011.

Intro: Gauss Elimination with Partial Pivoting. Gauss Elimination with Partial Pivoting is a direct method to solve the system of linear equations.. In this method, we use Partial Pivoting i.e. you have to find the pivot element which is the highest value in the first column & interchange this pivot row with the first row.
1.5 Gaussian Elimination With Partial Pivoting. In the previous section we discussed Gaussian elimination. In that discussion we used equation 1 to eliminate x 1 from equations 2 through n. Then we used equation 2 to eliminate x 2 from equations 2 through n and so on. In each case we used equation j to eliminate x j from equations j through n.
variable. The use of a certain equation to eliminate a variable from other equations is called a pivot and a rule 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 ...

Partial Pivoting: Usually sufficient, but not always Partial pivoting is usually sufficient Consider 2 2c 1 1 2c 2 With Partial Pivoting, the first row is the pivot row: 2 2c 0 1-c 2c 2-c and for large c: 2 2c 0 -c 2c-c so that y = 1 and x = 0. (exact is x = y = 1) The pivot is selected as the largest in the column, but it should be the
