I find the Timing results below a little curious. Is there a simple explanation why I shouldn't? Chris Grant In[1]:= x = Table[2.,{i,100000}]; In[2]:= y = Table[If[i<1000000,2.,i],{i,100000}]; In[3]:= SameQ[x,y] Out[3]= True In[4]:= Timing[Inner[Divide,x,x]] Out[4]= {0.44 Second,100000.} In[5]:= Timing[Inner[Divide,y,y]] Out[5]= {0.321 Second,100000.}
