Math Error[edit]
I don't think the update rule is correct. Shouldn't it be k/=j, rather than k = 1 to j?
Second User: I also believe the update rule is incorrect, however I believe it should be k = 1 to j-1. This is based on the "Matrix derivation" portion where they state that L is a matrix with zeros on or above the diagonal. I will search for corroborating evidence, then make the change if I find it. UPDATE: Nevermind, LT is defined as a matrix with 0s ABOVE the diagonal. It's a confusing equation + derivation! — Preceding unsigned comment added by 38.122.252.186 (talk) 14:22, 7 July 2015 (UTC)

vertically writtern vectors[edit]
It should be noted that x and y are vertically written vectors. The result of multiplications depends on that. — Preceding unsigned comment added by 80.218.32.215 (talk) 03:26, 21 January 2014 (UTC)
