When I use the example
Table[UnitStep[x], {x, -3, 3}]
I get
{UnitStep[-3],UnitStep[-2],UnitStep[-1],UnitStep[0],UnitStep[1],
UnitStep[2],UnitStep[3]}
and not
{0, 0, 0, 1, 1, 1, 1}
as the example in the online help suggests. DiracDelta[1] yields 0,
i.e. UnitStep should be defined (this was just a test whether or not
the package is loaded).
What is the problem?
Please respond by email, as well.
