Dear all,
Assume we have f[x_]:=f[x]=x^2 within some For[x=1,x<=3,x++...] loop.
At each iteration we assign a value to f[x] which results in a total
of three values.
I would like to delete at each iteration x the previous result of f.
Thus, we would only have a result of f[3] but not for the f[1] and
f[2].
This is a very simplified example but I think it describes my problem
well enough. The problem I have is that I generate via a loop a
massive amount of data in form of a list which I combine in one big
list but I don't need the intermediary results. At the moment
Mathematica 5.2 is always crashing and I think it has to do with these
lists.
I didn't us f[x-1]={} within the loop so far but I thought there might
be a more elegant way to handle the problem.
Thanks in advance,
Kristoph
