This caught me by surprise:
*julia> **M=rand(5,5)*
*5x5 Array{Float64,2}:*
* 0.621195 0.30108 0.611089 0.880044 0.779199*

*julia> **Matrix{Float64}[M M]*
*ERROR: MethodError: `convert` has no method matching
convert(::Type{Array{Float64,2}}, ::Float64)*
*This may have arisen from a call to the constructor Array{Float64,2}(...),*
*since type constructors fall back to convert methods.*
Closest candidates are:
call{T}(::Type{T}, ::Any)
convert{T,S,N}(::Type{Array{T,N}},
*::SubArray{S,N,P<:AbstractArray{T,N},I<:Tuple{Vararg{Union{AbstractArray{T,1},Colon,Int64}}},LD}*
)
convert{T,n}(::Type{Array{T,n}}, *::Array{T,n}*)

What's the correct way to do this? The following works but is not ideal:
*julia> **MM=Matrix{Matrix{Float64}}(1,2)*
*1x2 Array{Array{Float64,2},2}:*
* #undef #undef*
*julia> **MM[1,1]=M;MM[1,2]=M*
