initState()

The initState() method initializes the state variables of a UDA to a known state. If it is not called, all UDA state variables are automatically initialized to NULL.

Pass a table containing the initial values of the state variables to the initState() method. The initState() method returns the updated values.

Example

function initState(state)
    state[1] = 0
    state[2] = 0
    return state
end
