### Description

This block routes one of the regular inputs to the unique regular output. the choice of which input is to be routed is done, initially by the "initial connected input" parameter. Then, every time an input event arrives on the i-th input event port, the i-th regular input port is routed to the regular output.

### Dialog box

- number of inputs
  a scalar. Number of regular and event inputs.
  Properties : Type 'vec' of size 1

- initial connected input
  an integer. It must be between 1 and the number of inputs.
  Properties : Type 'vec' of size 1

### Default properties

- always active: yes
- direct-feedthrough: yes
- zero-crossing: no
- mode: no
- regular inputs:
  - port 1 : size [-1,1] / type 1
  - port 2 : size [-1,1] / type 1
- regular outputs:
  - port 1 : size [-1,1] / type 1
- number/sizes of activation inputs: 2
- number/sizes of activation outputs: 0
- continuous-time state: no
- discrete-time state: yes
- object discrete-time state: no
- name of computational function: relay
