How to sort a matrix in Julia

I am working with a matrix that looks like this in Julia: 

1-element Array{Array{Array{Int64,2},1},1}:
Array{Int64,2}[[14 32; 32 77]]

I want to sort the matrix in decreasing order just as I did in R with an output that looks like this: 

[1] 77 32 32 14

I tried using this function in Julia: 

[sort(z, rev=true)]

but I get the same matrix I started with, unsorted. Is it possible to sort a matrix in Julia so that it has a 1D output like in R?

In the same spirit:

m=[[14 32; 32 77]]
sort(collect(Iterators.flatten(m)), rev=true)

Output:

4-element Array{Int64,1}:
 77
 32
 32
 14

Do you mean something like this

m = [[14 32; 32 77]]
sort(hcat(m...)[:], rev=true)
