Hi, I would like to use N loops in a script for an arbitrary number of
loops using Cartesian. Do you know if that is possible?
E.g. :
julia> using Cartesian
julia> it=[-1.,0.,1.]
3-element Array{Float64,1}:
-1.0
0.0
1.0
julia> @nloops 3 i d->it begin
tp = @ntuple 3 i
println(tp)
end
(-1.0,-1.0,-1.0)
(0.0,-1.0,-1.0)
(1.0,-1.0,-1.0)
(-1.0,0.0,-1.0)
(0.0,0.0,-1.0)
(1.0,0.0,-1.0)
(-1.0,1.0,-1.0)
(0.0,1.0,-1.0)
(1.0,1.0,-1.0)
(-1.0,-1.0,0.0)
(0.0,-1.0,0.0)
(1.0,-1.0,0.0)
(-1.0,0.0,0.0)
(0.0,0.0,0.0)
(1.0,0.0,0.0)
(-1.0,1.0,0.0)
(0.0,1.0,0.0)
(1.0,1.0,0.0)
(-1.0,-1.0,1.0)
(0.0,-1.0,1.0)
(1.0,-1.0,1.0)
(-1.0,0.0,1.0)
(0.0,0.0,1.0)
(1.0,0.0,1.0)
(-1.0,1.0,1.0)
(0.0,1.0,1.0)
(1.0,1.0,1.0)
However
julia> N=3
3
julia> @nloops N i d->it begin
tp = @ntuple N i
println(tp)
end
ERROR: `_nloops` has no method matching _nloops(::Symbol, ::Symbol, ::Expr,
::Expr)
Is it possible to modify nloops so that it takes a variable for the number
of loops?
Thanks and best wishes,
Georgios
