Here is rookie question, which I have tried to find a similar question and
answer in the history of this group, but failed. Please bear me.
Since Julia distinguishes between Array{Float64,1} and Array{Float64,2},
even there is only one column in an Array{Float64,2}. Therefore, the type
of rand(5) and rand(5,1) are not same.
julia> x = rand(5)
5-element Array{Float64,1}:
0.183247
0.480208
0.623144
0.342792
0.0400695
julia> y = rand(5, 1)
5x1 Array{Float64,2}:
0.553224
0.0061835
0.762059
0.643796
0.655135
Is there any way that I can upgrade x about to become an Array{Float64,2}?
And is there a way to downgrade y to become an Array{Float64,1}, when it
has only one column?
In case that there is a similar discussion before, a link to the previous
thread is good enough and appreciated!
Thanks!
