Matrix mechanics

[jack47]

I was just wondering about Heisenbergs matrix mechanics, what does it look like? is it still usefull to solve certain problems? does anyone know a decent link that explains it properly? (I've had a look but found nothing detailed enough)

I know Hilbert proved it was equivalent to Schroedinger's method, but sometimes 2 equivalent methods can be very different when applied to certain situations.
