Question 1 Report

p = $| \begin{matrix} x & 3 & 0 \\ 2 & y & 3 \\ 4 & 2 & 4 \end{matrix} |$

q = $| \begin{matrix} x & 2 & z \\ 3 & y & 2 \\ 0 & 3 & z \end{matrix} |$

pq is equivalent to

ppT

pp-1

qp

pp

Answer Details

= $| \begin{matrix} 0 & 3 & 0 \\ 2 & 1 & 3 \\ 4 & 2 & 2 \end{matrix} |$
Q = $| \begin{matrix} 0 & 2 & 4 \\ 3 & 1 & 2 \\ 0 & 3 & 2 \end{matrix} |$ = pT
pq = ppT
