Hi, in principal you can unprotect UnitStep and redefine it. However, I would not advice this, but roll my onw by defining a new function with the desired features. hope this helps, Daniel solidifire wrote: > In Mathematica 3.0, UnitStep is defined in package > Calculus`DiracDelta` > and there is an option named ZeroValue, which enables the user to > define > the value of UnitStep[0]. > > http://documents.wolfram.com/v3/AddOns/Calc_DiracDelta-.html > or > http://tinyurl.com/35rtl7 > > In Mathematica 5.0, UnitStep is a built-in function and the default > value of UnitStep[0] is 1.
