val compare : ('a -> 'a -> int) -> 'a array -> 'a array -> int

First size comparison, then lexicographic order.

val equal : ('a -> 'a -> bool) -> 'a array -> 'a array -> bool

Lift equality to array type.

val equal_norefl : ('a -> 'a -> bool) -> 'a array -> 'a array -> bool

Like equal but does not assume that equality is reflexive: no optimisation is performed if both arrays are physically the same.

val is_empty : 'a array -> bool

True whenever the array is empty.

val exists2 : ('a -> 'b -> bool) -> 'a array -> 'b array -> bool
val for_all2 : ('a -> 'b -> bool) -> 'a array -> 'b array -> bool
val for_all3 : ('a -> 'b -> 'c -> bool) -> 'a array -> 'b array -> 'c array -> bool

val for_all_i : (int -> 'a -> bool) -> int -> 'a array -> bool
val findi : (int -> 'a -> bool) -> 'a array -> int option
val hd : 'a array -> 'a

First element of an array, or Failure "Array.hd" if empty.

val tl : 'a array -> 'a array

Remaining part of hd, or Failure "Array.tl" if empty.

val last : 'a array -> 'a

Last element of an array, or Failure "Array.last" if empty.

val cons : 'a -> 'a array -> 'a array

Append an element on the left.

val rev : 'a array -> unit

In place reversal.

val fold_right_i : (int -> 'b -> 'a -> 'a) -> 'b array -> 'a -> 'a
val fold_left_i : (int -> 'a -> 'b -> 'a) -> 'a -> 'b array -> 'a
val fold_right2 : ('a -> 'b -> 'c -> 'c) -> 'a array -> 'b array -> 'c -> 'c

val fold_left4 : ('a -> 'b -> 'c -> 'd -> 'e -> 'a) -> 'a -> 'b array -> 'c array -> 'd array -> 'e array -> 'a
val fold_left2_i : (int -> 'a -> 'b -> 'c -> 'a) -> 'a -> 'b array -> 'c array -> 'a
val fold_left_from : int -> ('a -> 'b -> 'a) -> 'a -> 'b array -> 'a
val map_to_list : ('a -> 'b) -> 'a array -> 'b list

Composition of map and to_list.

val map_of_list : ('a -> 'b) -> 'a list -> 'b array

Composition of map and of_list.

val chop : int -> 'a array -> 'a array * 'a array

chop i a returns (a1, a2) s.t. a = a1 + a2 and length a1 = n. Raise Failure "Array.chop" if i is not a valid index.

val split : ('a * 'b) array -> 'a array * 'b array
val map2_i : (int -> 'a -> 'b -> 'c) -> 'a array -> 'b array -> 'c array
val map3 : ('a -> 'b -> 'c -> 'd) -> 'a array -> 'b array -> 'c array -> 'd array
val map3_i : (int -> 'a -> 'b -> 'c -> 'd) -> 'a array -> 'b array -> 'c array -> 'd array
val map_left : ('a -> 'b) -> 'a array -> 'b array

As map but guaranteed to be left-to-right.

val iter2_i : (int -> 'a -> 'b -> unit) -> 'a array -> 'b array -> unit

Iter on two arrays. Raise Invalid_argument "Array.iter2_i" if sizes differ.

val iter3 : ('a -> 'b -> 'c -> unit) -> 'a array -> 'b array -> 'c array -> unit

Iter on three arrays. Raise Invalid_argument "Array.iter3" if sizes differ.

val fold_left_map : ('a -> 'b -> 'a * 'c) -> 'a -> 'b array -> 'a * 'c array

fold_left_map f e_0 [|l_1...l_n|] = e_n,[|k_1...k_n|] where (e_i,k_i)=f e_{i-1} l_i; see also Smart.fold_left_map

val fold_right_map : ('a -> 'c -> 'b * 'c) -> 'a array -> 'c -> 'b array * 'c

Same, folding on the right

val fold_left2_map : ('a -> 'b -> 'c -> 'a * 'd) -> 'a -> 'b array -> 'c array -> 'a * 'd array

Same with two arrays, folding on the left; see also Smart.fold_left2_map

val fold_left2_map_i : (int -> 'a -> 'b -> 'c -> 'a * 'd) -> 'a -> 'b array -> 'c array -> 'a * 'd array

Same than fold_left2_map but passing the index of the array

val fold_right2_map : ('a -> 'b -> 'c -> 'd * 'c) -> 'a array -> 'b array -> 'c -> 'd array * 'c

Same with two arrays, folding on the right

val distinct : 'a array -> bool

Return true if every element of the array is unique (for default equality).

val rev_of_list : 'a list -> 'a array

rev_of_list l is equivalent to Array.of_list (List.rev l).

val rev_to_list : 'a array -> 'a list

rev_to_list a is equivalent to List.rev (List.of_array a).

val filter_with : bool list -> 'a array -> 'a array

filter_with b a selects elements of a whose corresponding element in b is true. Raise Invalid_argument _ when sizes differ.

module Smart : sig ... end

The functions defined in this module are optimized specializations of the main ones, when the returned array is of same type as one of the original array.

module Fun1 : sig ... end

The functions defined in this module are the same as the main ones, except that they are all higher-order, and their function arguments have an additional parameter. This allows us to prevent closure creation in critical cases.
