$\%$Recall vectors are ordered n$-$tuples that can be represented as row or column vectors.

v$1=[2-1-113]$

v$2=[-32513]$

v$3=[7-4-713]$

$\%$Create a matrix C with the given vectors placed in the columns of C$.$

C $=[$v$1.\text{'}$ v$2.\text{'}$ v$3.\text{'}]$

$\%$Create the appropriately sized identity matrix, storing it in I.

I $=$ eye$(5)$

$\%$Augment C with the identity matrix.

augC $=[$C I$]$

$\%$Row reduce augC.

B $=$ rref$($augC$)$
