Is this easy enough?
julia> x = reshape(1:16, 4, 4)
4x4 Array{Int64,2}:
1 5 9 13
2 6 10 14
3 7 11 15
4 8 12 16
julia> a = x[1,:]
1x4 Array{Int64,2}:
1 5 9 13
julia> [a == x[k,:] for k = 1:size(x,1)]
4-element Array{Any,1}:
true
false
false
false
julia> any([a == x[k,:] for k = 1:size(x,1)])
true
julia> find([a == x[k,:] for k = 1:size(x,1)])
1-element Array{Int64,1}:
1
