Melee weapons use the power meter - the yellow meter near the top of the screen - to determine their damage. The damage of an attack is higher the more full the meter is when attacking.
Additionally, most attacks can be charged by holding the attack button. Charge is indicated by the power meter filling with blue, more charge on the meter will also increase the damage of an attack.
All melee weapons have a secondary attack which can perform a variety of functions, so give them a try!
