Hello, I would like to apply a function that I’ve created to an array/range. Let me use a simplified version of my code to illustrate my question. It starts defining a structure for parameters, something like: using Parameters @with_kw struct myParams α::Float64 = 0.5 β::Float64 = 0.5 end …

If you want your type to always act as a scalar, you can tell the broadcasting machinery to do that: Broadcast.broadcastable(mp::MyParams) = Ref(mp) Then myf.(range, p) should work. BTW, it’s a strong convention in Julia to make type names UpperCamelCase. So for clarity, you should probably call …
