[julia-users] Re: Can't use @manipulate in jupyter

Which version of Jupyter / IPython are you using? This is all going through an upheaval at the moment. My guess is that you need Pkg.checkout(Interact) to get the latest version of Interact.jl that works with version 3.0 of the Notebook. (But not, apparently, with the very latest version 4.0

[julia-users] Re: Splitting a multidimensional function

Here is a fun and possibly useful solution (that works only on 0.4 due to call overloading): https://gist.github.com/dpsanders/d8ef239ec8c78c4debee It introduces a `MultidimFunction` type, and a macro `@multidim` that works as follows: julia @multidim f(x) = [sqrt(x[1]), 2x[2]]

[julia-users] Re: Using composite types with many fields

Christoph's solution is neat. Another possibility is to just start with an empty object, by defining an inner constructor that does not define any of the fields, and then fill it up, as you were (IIUC) looking for. As far as I am aware, there is not any problem with doing this. type MyType
