How to call for custom functions in the compiled code? This involves calls for external user functions, recursive calls (perhaps recursive calls passing arguments by reference), or directly injecting code into a held Compile.Īs I'm in the process of understanding Compile, I have a very basic understanding at the moment.Is it efficient/safe to leave the compiler to deal with type-conversions? Type-conversions: Compile silently converts Integer/ Real input to the appropriate type, and it also packs non packed arrays, but I'm not sure what the cost of it is.Which practice is better: partition a large computation into smaller compiled functions, or wrap the whole into one big function? What factors should be considered when making a decision? One such factor is for example that a large compiled function cannot easily return intermediate values (at least it is not trivial how to do this, see this post, and perhaps it also decreases performance).x = x + c1 or x = c2, where the compiled function c2 contains the addition inside).
There are structures which are not allowed by the Mathematica virtual machine, e.g.Which functions are allowed in Compile (see these lists: functions, distributions)?.Some of these have already been answered (these don't need answers) but I included them for sake of clarity and completeness: What are the best practices of compiling functions? I understand that this is a vague question, but let me list some aspects that might trigger useful answers.
