Hi, I am trying to understand how to use eachindex with an array. For
example, I can do:
julia> A = zeros(Int, (3,2))
3x2 Array{Int64,2}:
0 0
0 0
0 0
followed by:
julia> for iter in eachindex(A)
@show iter.I[1], iter.I[2]
@show A[iter]
end
ERROR: type Int64 has no field I
[inlined code] from show.jl:127
in anonymous at no file:0
However, using:
julia> A = sprand(2, 3, 0.5)
2x3 sparse matrix with 2 Float64 entries:
[1, 1] = 0.599423
[2, 2] = 0.340233
julia> for iter in eachindex(A)
@show iter.I[1], iter.I[2]
@show A[iter]
end
(iter.I[1],iter.I[2]) = (1,1)
A[iter] = 0.5994230074532017
(iter.I[1],iter.I[2]) = (2,1)
A[iter] = 0.0
(iter.I[1],iter.I[2]) = (1,2)
A[iter] = 0.0
(iter.I[1],iter.I[2]) = (2,2)
A[iter] = 0.3402329840051479
(iter.I[1],iter.I[2]) = (1,3)
A[iter] = 0.0
(iter.I[1],iter.I[2]) = (2,3)
A[iter] = 0.0
works just fine. I'm sure it's something simple, but at this stage would
appreciate some help.
