Hi all,
I have this code with two types, one is an observation with a name, a time,
and a vector of observed values.
Another is a system where observations are stored, it comprises a list of
names nl which is an index of all the observation names, an observation
list ol which is a vector of tuples (t,v) where t is the time of an
observation and v is a vector of observed values. I also define a function
set to add the observation in the correct place in ol, i.e. at the index of
the name of this observation.
Maybe it will be clearer with some code:
type obs
n
t
v
end
type system
nl::Array{AbstractString}
ol::Array{Array{Tuple{Int64, Array{Float64}}}}
set::Function
function system(nl)
instance = new()
instance.nl = nl
instance.ol = Array(Array{Tuple{Int64, Array{Float64}}},
length(instance.nl))
fill!(instance.ol, Tuple{Int64, Array{Float64}}[])
instance.set = function(o)
push!(instance.ol[findfirst(instance.nl, o.n)], (o.t, o.v))
end
return instance
end
end
So now, if I try this very simple example:
o1 = obs("b",4,[1.0,3.0])
o2 = obs("c",6,[2.0,4.0])
nl = ["a","b","c"]
s = system(nl)
s.set(o1)
println(s.ol[1])
println(s.ol[2])
s.set(o2)
println(s.ol[1])
println(s.ol[2])
where I defined two observations, a system with a name list, and if I set
the two observations in my system, it puts each observation to everywhere
in ol, see the output:
Tuple{Int64,Array{Float64,N}}[(4,[1.0,3.0])]
Tuple{Int64,Array{Float64,N}}[(4,[1.0,3.0])]
Tuple{Int64,Array{Float64,N}}[(4,[1.0,3.0]),(6,[2.0,4.0])]
Tuple{Int64,Array{Float64,N}}[(4,[1.0,3.0]),(6,[2.0,4.0])]
where I was expecting something like:
Tuple{Int64,Array{Float64,N}}[(4,[1.0,3.0])]
Tuple{Int64,Array{Float64,N}}[]
Tuple{Int64,Array{Float64,N}}[(4,[1.0,3.0])]
Tuple{Int64,Array{Float64,N}}[(6,[2.0,4.0])]
Why is an observation pushed everywhere?
I should mention the fact that this code was working perfectly fine under
0.3.11 and I modified it so that it run under 0.4. (I mainly had to change
the Tuple syntax.)
Any idea would be welcome, thanks!
