Actually, I know the arrays allocated in every loop, my problem is that I
don't know the strategy to pre-allocate such arrays.
In short, this is the pre-allocating problem of arrays like array a
described below:
n = 1024; nt = 1000;
dt = 0.1
a = Array(Float64, n, n)
for i in 1:nt
t = i*dt
for j in eachindex(a)
a[j] = exp(pi * t) * a0
end
....... scripts to use a[j] for a single i........
end
In my problem, such arrays are hard to pre-allocate, do you have any
suggestions?
