Creating a 1x1 Julia array

I would like to create a 1×1 array (say an Array{Float64,2}) and initialize it to some value. Of course this works:

M=zeros(1,1)
M[1,1]=0.1234

Is there a more concise way to create M and initialize it at the same time?

The existing answers are not what I would recommend. The best way is to use

julia> hcat(5)
1×1 Array{Int64,2}:
 5

This is most concise and parallels the [x y] concatenation form.

An alternative is to reshape:

julia> reshape([1.234], 1, 1)
1x1 Array{Float64,2}:
 1.234

Since [1.1234] will give you a Vector in Julia the simplest way I could come up with is:

julia> fill(1.234,1,1)
1x1 Array{Float64,2}:
 1.234
