Load the Package Calculus`DiracDelta` and use the function In[56]:= ?UnitStep UnitStep[x] is a function that is 1 for x > 0 and 0 for x < 0. UnitStep[x1, x2, ...] is 1 for (x1 > 0) && (x2 > 0) && ... and 0 for (x1 < 0) || (x2 < 0) || ... . In[56]:= LaplaceTransform[UnitStep[t],t,s] 0.0166667 Second 1 Out[56]= - s regards, sergio rescia ------------------------------------- Reply to : Sergio Rescia Brookhaven National Laboratory Instrumentation Division - Bld 535B UPTON, NY 11973-5000 - U.S.A.
