What is meant by a pivot? What does pivoting do?

To determine

The definition of a pivot and the use of pivoting.

Explanation of Solution

Pivot is an entry in the matrix that is selected to ‘clear a column’. For the row reduction method always the first non-zero element of the row is selected as pivot. A pivot element is represented by putting a box around the element.

For example consider the matrix,

[11143115]

Select the first nonzero element of the first row as pivot.

[11143115]

Pivoting is the procedure of clearing the column using the selected pivot entry
