What can we achieve by combining both of them? [Slides](http://jul.github.io/cv/pres.html#/init) are here ## Introduction Algebra is a wonderful abstraction that make the infamous 2D point example ofa class or nameddict useless when you have complex data type (that is HWaccelerated on Intel CPU). ## I Algebra 101 : it is all about consistency between symbol and behaviour Simple: Is something consistent with linear algebra? it requires 17 simpleunit tests suffice to say so So just let makes a test this rules are followed, and then a class thatapplies these behaviours and we have implemented it. ## II I have linear algebra behaviour. How useful can it be? Well, you have basic data type like { x: 1, y :2, z :3 } that is actuallybehaving like an euclidean vector. If an object is a MutableMapping thus we can create a universal operator forsaying how much an object «looks like» another one.
