Hello, I have certain parts of my code that show up in a lot of functions. They are simple blocks of math like: a=x+2 b=a+3 ... And a and b are later used in different ways. One way of doing this is like this: function fun(x) a=x+2 b=a+3 return a,b # later in the code a,b=fun(x) but this gets c…

Maybe you wanted to define the macro as follows: macro mac(x) quote a=2*$x b=3*a end |> esc end

You can do this with macros . But I would personally find such a solution much messier than a proper use of functions. I think it’s much better to use functions, and if you have many variables that are used in many places, consider using named tuples or custom struct types.

Thanks. I couldn’t figure out a way to have a macro that puts variables in the scope where it’s called. I know you can make a variable in a macro global, but what I’d like is something like: function fun(x) for i=1:N @mac(x) vec[i] = a+b end end macro mac(x) a=2*x b=3*a end where a …

Works like a charm and it’s fast! Thanks!
