Type of y_out

[hombit]

Why type of y_out is Array{Array{T,1},1}? Maybe it should be 2-D array: Array{T,2}?

This was a concious decision based on discussions here and in other places. Basically, it's because the type of y0 could potentially be any type that supports a few basic mathematical operations, and not just scalar Numbers or vectors. In other words, there's no guarantee that y_out would fit in an Array{T,2}.

You can always get the matrix form by using hcat(y_out...) if that's important for you in the next step.

Thank you for the fast answer!
