val init : (int -> int -> elt) -> w:int -> h:int -> t

Maps from an array to another array of possibly different type. bw and bh arguments must be greater than 0 (they default to 1), for matrix w*h the last visited index is w-bw,h-bh.

val map : ?bw:int ->
       ?bh:int ->
       (int -> int -> elt -> 'a) -> t -> 'a array array

val iter : ?bw:int ->
       ?bh:int -> (int -> int -> elt -> unit) -> t -> unit

val fold : ?bw:int ->
       ?bh:int ->
       ('a -> int -> int -> elt -> 'a) -> 'a -> t -> 'a
