Extended functions
val (@) : 'a array -> 'a array -> 'a array

Operator of array concatenation.

val get_slice : int array -> 'a array -> 'a array

``get_slice slice x`` returns a copy of slice of ``x`` defined by ``slice``. The ``slice`` definition must have ``|start;stop;step|`` format. The value of start, stop, and step can be negative, and the boundary is inclusive.

val set_slice : int array -> 'a array -> 'a array -> unit

``set_slice slice x y`` sets the elements in ``x`` to the corresponding value of the elements in ``y`` based on the slice definition ``slice``. Please refer to ``get_slice`` function for the information on the format of slice definiton.

val iter2i : (int -> 'a -> 'b -> 'c) -> 'a array -> 'b array -> unit

TODO

val iter2 : ('a -> 'b -> 'c) -> 'a array -> 'b array -> unit

TODO

val iter3i : (int -> 'a -> 'b -> 'c -> 'd) -> 'a array -> 'b array -> 'c array -> unit

TODO

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

TODO

val filteri_v : (int -> 'a -> bool * 'b) -> 'a array -> 'b array

TODO

val filter_v : ('a -> bool * 'b) -> 'a array -> 'b array

TODO

val filteri : (int -> 'a -> bool) -> 'a array -> 'a array

``filteri f x`` filters out the elements in ``x`` according to predicate ``f``.

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

``filter f x`` filters out the elements in ``x`` according to predicate ``f``.

val filter2i : (int -> 'a -> 'b -> bool) -> 'a array -> 'b array -> ('a * 'b) array

``filter2i f x y`` filters the elements in ``x`` and ``y`` using passed in function ``f``. Both arrays must have same length.

val filter2 : ('a -> 'b -> bool) -> 'a array -> 'b array -> ('a * 'b) array

``filter2 f x y`` is similar to ``filter2i`` but without passing index of the elements to function ``f``.

val filter2i_i : (int -> 'a -> 'b -> bool) -> 'a array -> 'b array -> int array

``filter2i_i f x y`` filters the elements in ``x`` and ``y`` using passed in function ``f``. Both arrays must have same length. Note that the indices of those satisfying the predicate ``f`` are returned in an array.

val filter2_i : ('a -> 'b -> bool) -> 'a array -> 'b array -> int array

``filter2_i f x y`` is similar to ``filter2i_i`` but without passing index of the elements to function ``f``.

val resize : ?head:bool -> 'a -> int -> 'a array -> 'a array

``resize ~head v n x`` resizes ``x`` of length ``m`` to length ``n``. If ``m <= n``, a copy of ``x`` subarray is returned. If ``m > n``, then ``x`` is extended, the extra space is filled with value ``v``.

val pad : [ `Left | `Right ] -> 'a -> int -> 'a array -> 'a array

TODO

val align : [ `Left | `Right ] -> 'a -> 'a array -> 'a array -> 'a array * 'a array

``align side v x y`` aligns two arrays ``x`` and ``y`` along the specified side with value ``v``. The copies of two arrays are returned.

val greater_eqaul : 'a array -> 'a array -> bool

TODO

val swap : 'a array -> int -> int -> unit

TODO

val permute : int array -> 'a array -> 'a array

TODO

val of_tuples : ('a * 'a) array -> 'a array

TODO

val complement : 'a array -> 'a array -> 'a array

TODO

val balance_last : float -> float array -> float array

``balance_last mass x`` performs the following function. Let ``k`` be the length of ``x``, if ``i < l - 1``, then ``x.(i) = x.(i)``, otherwise ``x.(l - 1) = mass - \sum x.(i)``.

val index_of : 'a array -> 'a -> int

``index_of x a`` returns the index of first occurrence of ``a`` in ``x``.

val to_string : ?prefix:string -> ?suffix:string -> ?sep:string -> ('a -> string) -> 'a array -> string

TODO
