Question

is there a way to iterate list over the list through List.map?

I know List.map takes single function and list and produce a list that the function applies to all elements. But what if i have a list of function to apply a list and produce list of the list ?

Answer 1

Your question is not very clear, however as far as I understand it, you have a list of functions and a list of values. If you want to apply all functions to all elements then you can write this:

(* // To get one nested list (of results of all functions) for each element *)
List.map (fun element ->
  List.map (fun f -> f element) functions) inputs

(* // To get one nested list (of results for all elements) for each function *)
List.map (fun f ->
  List.map (fun element -> f element) inputs) functions

In case this is not what you wanted, could you try clarifying the question a little bit (perhaps some concrete example would help)?
