Stateflow

Entering Multiline Labels

In the examples shown thus far of entering labels for states and transitions, only a simple one-line expression has been used. The following figure shows state A with a multiline label.

There are two ways to enter multiline labels for both states and transitions. In the following examples, sA is a workspace variable handle to the State object in the Stateflow API for state A.

• Use the MATLAB function sprintf:

• str = sprintf('A\nen: entrA()\ndu: duriA()\nex: exitA()')
  sA.LabelString = str
  

• In this example, carriage returns are inserted into a string expression with the escape sequence \n.

• Use a concatenated string expression:

• str = ['A',10,'entr: entrA()',10,'du: duriA()',10,'ex: exitA()']
  sA.LabelString = str
  

• In this example, carriage returns are inserted into a concatenated string expression with the ASCII equivalent of a carriage return, the integer 10.
