-

Matrix

i, j

-

integers; position of the pivot entry

options

-

(optional) parameters; for a complete list, see LinearAlgebra[Pivot]

Description

• 

The Pivot(A, i, j) command pivots A about the nonzero entry Ai,j.  Multiples of the ith row are added to every other row in A, with the result that all entries in the jth column of A are zero except for the i,jth element.

Examples
