[julia-users] Writable arrays

In a function that modifies an array argument I would like to pass at least (Dense)Arrays and SubArrays (from `slice`). AbstractArray is too broad a type -- a LinSpace does not allow changing an entry. What would be a suitable class? Union{DenseArray, SubArray} works, but is there a better

I have a custom type with a TypePar denoting a dimension and would like to define the following: type Foo{D} bar::Array{D+1} end However, this does not work. As D is only 1 or 2 it would OK with type Foo{1} bar::Matrix end type Foo{2} bar::Array{3} end but unfortunately this isn't working,

[julia-users] Re: Function check without @assert

Thanks a lot for the explanations! I'll stick with the throwing for now. I'm using Julia v0.4.0 which does not seem to have the @check / @require. I'm compiling v0.4.5 now to see if that includes these macros.

I've become fond of using the @assert macro for checking input to functions, e.g. @assert size(A) == size(B) @assert x > 0 Now I've read discussions like https://github.com/JuliaLang/julia/issues/10614 where I see that this not recommended and that @assert is slow. What is then the "right"
