Hi,
If I define a recursion and hold its form to inspect it :
Clear[test]
test[j_Integer?Positive] :=
test[j] = k[j] HoldForm[ test[j - 1] ]
then This is what happens :
In[22]:= test[4]
Out[22]:= test[4 - 1] k[4]
But I would like it to be with the variable evaluated :
Out[22]:= test[3] k[4]
Whats the trick ???
thanks
Matt
