Harvard AM205 video 2.9 - Householder triangularization

[@holyshit922]

In my opinion in video is missing explanation of effective multiplication by H matrices
I dont want to use extra O(n^2) space for H matrices and high school matrix multiplication because it will be too costly
Moreover I would like to use Householder reflections to Hessenberg reduction and
for generating orthogonal polynomials
