Switch

Set the output state to one among \(n\) input states, based on the value of a controlling state.

Syntax:

• function name: switch
• input variable : \(x_i(l), l \in \{1, 2, ... , n \}\)
• variable \(x_k\)
• variable \(x_j\)

Internal states : none

Discrete variable : \(z \in \{1, 2, ... , n \}\)

Equations

\[ 0 = x_j - x_i(z) \]

Discrete transitions

z ← max(1, min(n, nint(xk)))

where nint function returns the nearest integer.

Initialisation of discrete variables

Same code as for the discrete transitions.
