This function returns an elementary cumul function expression that is equal to v between start and end and equal to 0 everywhere else.

This function returns an elementary cumul function expression that, whenever interval variable a is present, is equal to v between the start and the end of interval variable a and equal to 0 everywhere else. When interval variable a is absent, the function is the constant zero function.

This function returns an elementary cumul function expression that, whenever interval variable a is present, is equal to a value v such that vmin <= v <= vmax everywhere between the start and the end of interval variable a and equal to 0 everywhere else. The choice of the value v in the range [vmin,vmax] is a decision of the problem. When interval variable a is absent, the function is the constant zero function.
