Parentheses ( ) in the syntax means that you must add a
parameter.
For example, the following function requires two variable
parameters that contain the stress and strain data. The start and
end indexes for loading and unloading modulus calculations are
optional because they are in square brackets:
CycleModulus(Stress,Strain[,
startIndexLoading,endIndexLoading, startIndexUnloading,
endIndexUnloading])
