“I don’t suppose any of you know how to decompose a Gaussian function into row and column vectors, eh?

Gaussian filters have a nice property in that they are separable into two vectors, but I can’t figure out how, given a Gaussian matrix, one derives the component vectors.

“of course i do..don’t be ridiculous everyone knows how to decompose a Gaussian Function. Don’t feed it for a week..it dies, then decomposes..simple.
