In[1]:= Heaviside[0] Out[1]= Heaviside[0] In[2]:= UnitStep[0] Out[2]= 1 I don't know if a separate unit_step is necessary, but I am not a fan of aliases. :) Cheers, Burcin --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
