i sort of figured out how to do this a few mins ago lol. it doesn't seem too hard.

it's sort of like... multiplying the first number in the matrix A by it's position in the matrix (x1 * x1) which is basically the coordinates of the value, then doing that for all numbers in the matrix A.

am i right? have i fully answered the question?

edit: in my working out, the x

^{T}Ax = sigma sigma axx was taken from my course manual.
