title: Simulink Convert Single to 4 Bytes
body: <p>I want to convert a single to 4 bytes in order to send them by serial port.
  for example <code>30:0x41 0xF0 0x00 0x00</code>
  I don't know if a <code>Simulink</code> block already exists or if I should create a <code>matlab function</code> for this aim.</p>
