function B $=$ myPivot$($A$,$i$,$j$)$

$\%$myPivot $-$ Pivots a matrix A at entry $($i$,$j$).$

$\%$

$\%$ B $=$ myPivot$($A$,$i$,$j$)$ produces a matrix B that is row equivalent to A

$\%$ where B$($:$,$j$)=0$ except for B$($i$,$j$)=1.$

$\%$

$\%$ Inputs:

$\%$ A $-$ a matrix

$\%$ i $-$ row index to pivot

$\%$ j $-$ column index to pivot

$\%$

$\%$ Outputs:

$\%$ B $-$ a matrix that is row equivalent to A and has been pivotted about

$\%$ entry $($i$,$j$).$

$\%\%$ Welcome to LAB $2$

$\%$ In lab$2$ we will write code to reduce a matrix to row echelon form. In

$\%$ particular, we will make functions that pivot an entry of a matrix and

$\%$ reduce matrices to reduced row echelon form.

$\%$ In class we saw how to use:

$\%-$ boolean operations $($True False$)$

$\%-$ use if$-$then logic

$\%-$ write custom functions

$\%-$ access custom functions

$\%\%$ Pivoting

$\%$ Please finish your myPivot code and ensure that it works properly

A $=[[3428]$;$[1-2510]$;$[3-158]]$;

myPivot$($A$,1,1)$

myPivot$($A$,2,3)$
