output is one element tuple vector. I can’t access the elements of that output.  
so, how to convert output to a 3x1 matrix.  
Thank You

```julia
only(s)

```

should give you a tuple, why do you need to convert it to a matrix?

`reduce(vcat,only(s))` or `vcat(only(s)...)` will convert it to a 3-vector, which should be compatible with a 3x1 matrix almost everywhere unless you have typed some functions too strictly. You can apply an additional `reshape(thevector,3,1)` if you insist on it being a matrix rather than vector.
