The big problem is that there are no single set of rules - the way things work (row/column orders, how results should be presented etc) change depending upon the application. You could implement "general vector operations" or "general matrix operations" but then you have to decide *which* general ones to implement - the ones that mathematicians prefer, the ones used by 3D procgrammers (which are slightly different) etc. I expect one of the reasons RT have avoided this issue is simply because matrix maths are such a thorny area...
