I’ve designed a set of factorization diagram cards and had them actually printed. This is one of the first times in my life when I have caused Actual Physical Objects to be created (other than using a printer I guess) so this is a pretty big deal for me! 36 more words

#### Factorization

Playing around with prime numbers, I created this simple factorization program.

The interesting thing about prime factors is that they are unique. There can only be one way to multiply prime numbers to get where and (excluding the commutative property). 64 more words

#### Cholesky updates of A'A

Updating the Cholesky factorization of when one or more columns are added to or removed from matrix can be done very efficiently obviating the re-factorization from scratch. 303 more words
