How do I implement a delay in Stateflow?

I want to implement the equivalent of the Delay block from the Discrete Library of Simulink inside a Stateflow chart. My inputs can be a scalar, vector, matrix or a time varying signal.

[MathWorks Support Team]

Delays may be implemented inside a Stateflow chart using transitions and temporary variables. Download the attached models (delaystate.mdl and delaystate1.mdl) and compare the simulation results obtained using delay blocks and the Stateflow chart.

Notes:

1. The number of temporary variables is equal to the number of times the input needs to be delayed.

2. The temporary variables in Stateflow charts cannot be used to resolve algebraic loops, like Unit-Delay Blocks (refer delaystate2.mdl).

Same model I am trying to implement but it is keep showing me error " Size for Local Data 'temp' may not be inherited" I tried to copy all the variable property of chart but even i am unable to develop same model.
