Data provides some extra operations for Bigarray.Array1

type ('a, 'b) t = ('a, 'b, Stdlib.Bigarray.c_layout) Stdlib.Bigarray.Array1.t

Data type

val ty : ('a, 'b) t -> ('a, 'b) Type.t

Get the Bigarray.ty

val of_array : ('a, 'b) Type.t -> 'a array -> ('a, 'b) t

Converts an array to a Data.t of the given ty

val to_array : ('a, 'b) t -> 'a array

Converts a Data.t to an array

val v : ('a, 'b) Type.t -> int -> ('a, 'b) t

Create a new Data.t with the given length.

val random : ('a, 'b) Type.t -> int -> ('a, 'b) t
val length : ('a, 'b) t -> int

Returns the number of elements in a Data.t

val fold2 : ('a -> 'd -> 'c -> 'c) -> ('a, 'b) t -> ('d, 'e) t -> 'c -> 'c

Reduce over two Data.t

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

Reduce over a single Data.t

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

fill d x sets each value of d to x

val map_inplace : ('a -> 'a) -> ('a, 'b) t -> ('a, 'b) t

map_inplace f data runs f over each value of data

val map2_inplace : ('a -> 'c -> 'a) -> ('a, 'b) t -> ('c, 'd) t -> ('a, 'b) t

map2_inplace f data1 data2 runs f over each value of data1 and data2

val slice : offs:int -> length:int -> ('a, 'b) t -> ('a, 'b) t

slice ~offs ~length data extracts a section of data of length values starting at index offs

val copy_to : dest:('a, 'b) t -> ('a, 'b) t -> unit

copy_to ~dest src copies each value from src to dest

val copy : ('a, 'b) t -> ('a, 'b) t

Create a new copy of Data.t

val convert : ('c, 'd) Type.t -> ('a -> 'c) -> ('a, 'b) t -> ('c, 'd) t

Convert between Data.t types

val convert_to : ('a -> 'c) -> dest:('c, 'd) t -> ('a, 'b) t -> unit

Convert between Data.t types with an existing destination image

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

Default hash function

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

Default comparison function

val equal : ('a, 'b) t -> ('a, 'b) t -> bool

Default equality function
