Hi all
I want to create matrix containing dot products
julia> X = rand(5,5)
5x5 Array{Float64,2}:
0.274799 0.564619 0.915595 0.341059 0.57361
0.0806822 0.293939 0.379279 0.608582 0.652441
0.264678 0.532751 0.289088 0.457759 0.492777
0.33856 0.495587 0.499099 0.548237 0.402534
0.686305 0.168385 0.8322 0.605532 0.518693
julia> K = [dot(X[:,i], X[:,j]) for i=1:5, j=1:5]
5x5 Array{Any,2}:
0.737716 0.603229 1.09884 0.865174 0.832958
0.603229 0.962978 1.16994 0.988988 1.06501
1.09884 1.16994 2.00739 1.45298 1.54767
0.865174 0.988988 1.45298 1.36347 1.35304
0.832958 1.06501 1.54767 1.35304 1.42861
I expect to get an Array{Float64,2}, but what I got is Array{Any,2}.
How to get Array{Float64,2} using Array comprehension?
Thanks before
Rizal
