Thanks! actually saw the first A.Ng lectures already, and he framed all concepts by way of linear algebra, which made me stumble on just the second video

  Then you know where to start. Read a good linear algebra text; I'd suggest Strang. He also has lectures online. If you stumble on those, do what I just suggested for whatever you stumble on.

    a recursive solution (or is it?), thanks!

  Definitely give the courses I've mentioned in another comment a try - the material will make a lot more sense. Also keep in mind that Andrew Ng is a rather poor lecturer and many of his explanations are unclear or incomplete.
