Incidentally intervoxel, I just took out of copy of Herbert S. Green's Matrix Mechanics (1965) and it looks like a good introduction to what you were talking about, although for the moment I don't have a clear idea of how vectors and matrices are isomorphic to waves and functions of waves. But I am just beginning to study all this.

QM isn't trivial stuff anyway, but the journey is worthwhile (I'm a beginner too).
Interestingly, while Griffiths goes from wave functions to vectors, Sakurai starts with vectors and eventually defines wavefunctions as projections of the state vectors on a suitable basis.
Good luck, snoopies622.
