If you don't need the square root, sumabs2 is even more efficient and can work
over dimensions.

It seems you're trying to compute a dot product. Try dot(M[:,1], M[:,1]) or
norm(M[:,1]). Of course, as a side comment, that quantity can't be negative ;).
When i do:
M=rand(5,5)
a=M[:,1]' * M[:,1]
if a<0
println("Less than 0")
else
println("more")
end
I have an error: " isless has no method matching isless(::Array{Float64,2},
::Int 32) in < at operators.jl:32
Can anyone tell me please how to do this? Thank you
