You could just draw in the value of k outside the pattern match: k = 5; f[j_] := rhs[k, j]; f[4] zahava asked: > > An assignment using SetDelayed, lhs := rhs, maintains rhs in completely > unevaluated form. > Thus, if k=5, say, the assignment > > In[1] = f[k,j_]:=rhs[k,j] > > yields > > In[2] = ?f > Global`f > f[5,j_]:=rhs[k,j] > > How can I force the k on the right hand side to be evaluated so that ?f > will yield > f[5,j_]:=rhs[5,j] ? > > Of course, I could define f[5,j_] manually, but I want to automate the > procedure over a range of values of k. >
