step(double height, double stepTime)
Returns 0 until the stepTime and then returns height.
The plot below illustrates how the function works:
Name Type Description height double The height of the step. stepTime double The time of the step.
Type Description double 0 until the stepTime and then returns height.
height — units
stepTime — time
step() — units
You can study the "Multiplier Simul Eqns" example model to understand the function usage. The step() function is used in the formula of the GovernmentExpenditure dynamic variable: GovernmentExpenditure = 90 + step( 10, 1 ). If you run the model and switch to the "Graphs" page, you will see how the step logic affects the system behavior at the time 1.
