1. Sequence Multiplication
Where length(seq_a) = length(seq_b), instead of
seq_x = seq_a * seq_b
should I use
for t=1 to length(seq_a) do
seq_x[t] = seq_a[t] * seq_b[t]
end for
I would try it out but it's late and I'm going to bed. Plus, someone may
have some additional insights they'd like to share.
Thanks (and goodnight),

If seq_a and seq_b are short (and what qualifies as 'short' varies from
machine to machine), the former is the faster method.
For longer seq_a and seq_b, the latter is faster.
However, if you can, use one of these instead of the latter:
-- This has the disadvantage of destroying the original seq_a
for t = 1 to length(seq_a) do
seq_a[i] *= seq_b[i]
end for
seq_x = repeat(0, length(seq_a)) do
for t = 1 to length(seq_a) do
seq_x[i] = seq_a[i] * seq_b[i]
end for
