Can you give us the PSO function that you're trying to call? It's unclear
what you really need:
# here each object just holds a pair of values
type DB
Y::Complex128
w::Float64
end
# and fill in the structure like:
data = Array(DB, 100) # creates Array{DB,1} with space for 100 DB
elements, but no actual data yet
for i in 1:100
data[i] = DB(mycomplexnum, myfloatnum)
end
# or you could do
data = DB[] # creates empty Array{DB,1}
for i in 1:100
push!(data, DB(mycomplexnum, myfloatnum)
end
Or if you want 1 structure to just hold pointers to an Array{Complex128,1}
and an Array{Float64,1}, then use something like Kaj's answer.
Either way, I think we need to see the function you want to call to help
further.
