Bigarray.Array3

# Module Bigarray.Array3

    module Array3: sig .. end

Three-dimensional arrays. The `Array3` structure provides operations similar to those of `Bigarray.Genarray`, but specialized to the case of three-dimensional arrays.

    type ('a, 'b, 'c) t

The type of three-dimensional big arrays whose elements have OCaml type `'a`, representation kind `'b`, and memory layout `'c`.

    val create : ('a, 'b) Bigarray.kind ->
           'c Bigarray.layout -> int -> int -> int -> ('a, 'b, 'c) t

`Array3.create kind layout dim1 dim2 dim3` returns a new bigarray of three dimension, whose size is `dim1` in the first dimension, `dim2` in the second dimension, and `dim3` in the third. `kind` and `layout` determine the array element kind and the array layout as described for `Bigarray.Genarray.create`.

    val dim1 : ('a, 'b, 'c) t -> int

Return the first dimension of the given three-dimensional big array.

    val dim2 : ('a, 'b, 'c) t -> int

Return the second dimension of the given three-dimensional big array.

    val dim3 : ('a, 'b, 'c) t -> int

Return the third dimension of the given three-dimensional big array.

    val kind : ('a, 'b, 'c) t -> ('a, 'b) Bigarray.kind

Return the kind of the given big array.

    val layout : ('a, 'b, 'c) t -> 'c Bigarray.layout

Return the layout of the given big array.

    val get : ('a, 'b, 'c) t -> int -> int -> int -> 'a

`Array3.get a x y z`, also written `a.{x,y,z}`, returns the element of `a` at coordinates (`x`, `y`, `z`). `x`, `y` and `z` must be within the bounds of `a`, as described for `Bigarray.Genarray.get`; otherwise, `Invalid_argument` is raised.

    val set : ('a, 'b, 'c) t -> int -> int -> int -> 'a -> unit

`Array3.set a x y v`, or alternatively `a.{x,y,z} <- v`, stores the value `v` at coordinates (`x`, `y`, `z`) in `a`. `x`, `y` and `z` must be within the bounds of `a`, as described for `Bigarray.Genarray.set`; otherwise, `Invalid_argument` is raised.

    val sub_left : ('a, 'b, Bigarray.c_layout) t ->
           int -> int -> ('a, 'b, Bigarray.c_layout) t

Extract a three-dimensional sub-array of the given three-dimensional big array by restricting the first dimension. See `Bigarray.Genarray.sub_left` for more details. `Array3.sub_left` applies only to arrays with C layout.

    val sub_right : ('a, 'b, Bigarray.fortran_layout) t ->
           int -> int -> ('a, 'b, Bigarray.fortran_layout) t

Extract a three-dimensional sub-array of the given three-dimensional big array by restricting the second dimension. See `Bigarray.Genarray.sub_right` for more details. `Array3.sub_right` applies only to arrays with Fortran layout.

    val slice_left_1 : ('a, 'b, Bigarray.c_layout) t ->
           int -> int -> ('a, 'b, Bigarray.c_layout) Bigarray.Array1.t

Extract a one-dimensional slice of the given three-dimensional big array by fixing the first two coordinates. The integer parameters are the coordinates of the slice to extract. See `Bigarray.Genarray.slice_left` for more details. `Array3.slice_left_1` applies only to arrays with C layout.

    val slice_right_1 : ('a, 'b, Bigarray.fortran_layout) t ->
           int -> int -> ('a, 'b, Bigarray.fortran_layout) Bigarray.Array1.t

Extract a one-dimensional slice of the given three-dimensional big array by fixing the last two coordinates. The integer parameters are the coordinates of the slice to extract. See `Bigarray.Genarray.slice_right` for more details. `Array3.slice_right_1` applies only to arrays with Fortran layout.

    val slice_left_2 : ('a, 'b, Bigarray.c_layout) t ->
           int -> ('a, 'b, Bigarray.c_layout) Bigarray.Array2.t

Extract a two-dimensional slice of the given three-dimensional big array by fixing the first coordinate. The integer parameter is the first coordinate of the slice to extract. See `Bigarray.Genarray.slice_left` for more details. `Array3.slice_left_2` applies only to arrays with C layout.

    val slice_right_2 : ('a, 'b, Bigarray.fortran_layout) t ->
           int -> ('a, 'b, Bigarray.fortran_layout) Bigarray.Array2.t

Extract a two-dimensional slice of the given three-dimensional big array by fixing the last coordinate. The integer parameter is the coordinate of the slice to extract. See `Bigarray.Genarray.slice_right` for more details. `Array3.slice_right_2` applies only to arrays with Fortran layout.

    val blit : ('a, 'b, 'c) t -> ('a, 'b, 'c) t -> unit

Copy the first big array to the second big array. See `Bigarray.Genarray.blit` for more details.

    val fill : ('a, 'b, 'c) t -> 'a -> unit

Fill the given big array with the given value. See `Bigarray.Genarray.fill` for more details.

    val of_array : ('a, 'b) Bigarray.kind ->
           'c Bigarray.layout -> 'a array array array -> ('a, 'b, 'c) t

Build a three-dimensional big array initialized from the given array of arrays of arrays.

    val map_file : Unix.file_descr ->
           ?pos:int64 ->
           ('a, 'b) Bigarray.kind ->
           'c Bigarray.layout ->
           bool -> int -> int -> int -> ('a, 'b, 'c) t

Memory mapping of a file as a three-dimensional big array. See `Bigarray.Genarray.map_file` for more details.

    val unsafe_get : ('a, 'b, 'c) t -> int -> int -> int -> 'a

Like `Bigarray.Array3.get`, but bounds checking is not always performed.

    val unsafe_set : ('a, 'b, 'c) t -> int -> int -> int -> 'a -> unit

Like `Bigarray.Array3.set`, but bounds checking is not always performed.
