Voltage regulator Capacitor values ... ?

Hello
i keep on wondering how to determine Capacitor values for input and output of a voltage regulator
for instance , right now i'm using 7809. the datasheet and the engineers around me are giving me different values for the VR input C and output
for instance some say for input
330N ,
0.1u
output
10u
1N
100N

unless there is no definete mechanism \ formula \theory on this
just the bigger capacitor the better ?
