If I write a function in Julia that returns an object x with multiple fields, is there any way to call the values of specific fields of that object? I am not sure how to do this, as the variable name will specifically be local to the function; I have attached an image further explaining this.
Your variable is local (within function scope) and perhaps you want to have a global variable.
function c1()
Data(10 ,20)
end
function c2()
global z2 = Data(100 ,200) # note that using globals is discouraged in Julia
end
Now you have:
julia> z1 = c1(); # recommended approach
julia> z1.x
10
julia> c2();
julia> z2.x
100
