Calculate the indicated products of row vector v and matrix A.
You can report your results as simple row-by-row listings of
elements, using tabs or spaces to separate the elements, as done
below for matrix A.
v = [ 5 3 1 ] A= 0 1 2
2 1 1
a) v ⋅ AT
b) A ⋅ AT
c) AT ⋅ A
d) A ⋅ vT
e) Explain why the answers to a) and d) are similar, using the
transposition rule
