I'm following the quickstart guide on JuMP.
My julia version is 0.7, the code is this:
using JuMP
m = Model()
l = zeros(10)
u = ones(10)
#@variable(m, x)
#@variable(m, 0 <= x[1:10] <= 1)
@variable(m, l<=x[1:10]<=u)
The first two variable macros (commented out) work fine, but the last one produces an error.
MethodError: no method matching constructvariable!(::Model, ::getfield(JuMP, Symbol("#_error#107")){Tuple{Symbol,Expr}}, ::Array{Float64,1}, ::Array{Float64,1}, ::Symbol, ::String, ::Float64)
Closest candidates are:
constructvariable!(::Model, ::Function, !Matched::Number, !Matched::Number, ::Symbol, ::AbstractString, ::Number; extra_kwargs...) at /home/lhk/.julia/packages/JuMP/Xvn0n/src/macros.jl:968
constructvariable!(::Model, ::Function, !Matched::Number, !Matched::Number, ::Symbol, !Matched::Number, !Matched::Array{T,1} where T, !Matched::Array{Float64,1}, !Matched::AbstractString, !Matched::Number; extra_kwargs...) at /home/lhk/.julia/packages/JuMP/Xvn0n/src/macros.jl:961

How can I have different bounds for each entry in a vector valued variable ?
Argh, this is actually really easy:
l = zeros(10)
u = ones(10)
@variable(m, l[idx] <= x[idx = 1:10] <= u[idx])
