Hi.
I'm trying to do most trivial and simple thing - define
some function and then Plot[] it. However, I get some very
weird error - " ...is not a machine-size real number at ..."
Here is the code :
a[0]==1
a[1]==0.99/50000
H[w] == 20Log[10,Sum[a[k] Exp[I 2Pi w(-k)], {k,0,1}]]
Clear[H]
Plot[H[w], {w, 1, 100}]
I've seen some articles (even at www.wolfram.com) about that
problem, but NONE of them proposed a working solution !!!
Just putting Evaluate[] inside the Plot[] does nothing...
