val create : ('a'b) Stdlib.Bigarray.kind -> 'c Stdlib.Bigarray.layout -> int -> int -> ('a'b'c) Stdlib.Bigarray.Array2.t
type 'l complex_array = (Stdlib.Complex.t, complex_elt'l) Stdlib.Bigarray.Array2.t

Double precision complex 2D array.

type 'l float_array = (float, float_elt'l) Stdlib.Bigarray.Array2.t

Double precision float 2D array.

type coord = int * int

Coordinates of emlements of the 2D array.
