I have a multi dimensional array in julia:

julia> ac.value
3x100x3 Array{Float64,3}:
[:, :, 1] =
 0.29238   0.0751815  0.00843636   …  -0.0143826   0.0403283  0.0225896
 0.263146  0.080687   0.000462262     -0.00635778  0.0307563  0.0379104
 0.992458  0.986423   0.980587         0.561173    0.55516    0.549105 

[:, :, 2] =
 0.362155  0.13406   0.0741124  …   0.0231614   0.0156455   0.0121797
 0.325581  0.11181   0.0447847      0.0098042   0.0193873   0.0146943
 0.914888  0.852297  0.796608      -0.0500265  -0.0551787  -0.0520171

[:, :, 3] =
 0.269976  0.108082   0.0441809  …  0.0249861  0.0128778   0.0168318 
 0.218475  0.0997567  0.0532782     0.0243412  0.00742072  0.00978782
 0.96878   0.947455   0.931407      0.0796884  0.0710757   0.0630705 

When I look at

julia> ac.value[1,:,1]
1x100 Array{Float64,2}:
 0.29238  0.0751815  0.00843636  …  -0.0143826  0.0403283  0.0225896

I get a 2 dimensional array, but when I look at

julia> ac.value[:,1,1]
3-element Array{Float64,1}:
 0.29238 
 0.263146
 0.992458

I get a one dimensional array. What can I do so that in the former case I get a one-dimensional array?
