Module Array3
: sigend
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 Bigarrays whose elements have OCaml type 'a , representation kind 'b , and
memory layout 'c .
valcreate : ('a,'b)Bigarray.kind->'cBigarray.layout->int->int->int->('a,'b,'c)tArray3.createkindlayoutdim1dim2dim3 returns a new Bigarray of three dimensions, 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 .
valinit : ('a,'b)Bigarray.kind->'cBigarray.layout->int->int->int->(int->int->int->'a)->('a,'b,'c)tArray3.initkindlayoutdim1dim2dim3f returns a new Bigarray b of three dimensions, 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 .
Each element Array3.getbijk of the array is initialized to the result of fijk .
In other words, Array3.initkindlayoutdim1dim2dim3f tabulates the results of f applied to the
indices of a new Bigarray whose layout is described by kind , layout , dim1 , dim2 and dim3 .
Since 4.12
valdim1 : ('a,'b,'c)t->int
Return the first dimension of the given three-dimensional Bigarray.
valdim2 : ('a,'b,'c)t->int
Return the second dimension of the given three-dimensional Bigarray.
valdim3 : ('a,'b,'c)t->int
Return the third dimension of the given three-dimensional Bigarray.
valkind : ('a,'b,'c)t->('a,'b)Bigarray.kind
Return the kind of the given Bigarray.
vallayout : ('a,'b,'c)t->'cBigarray.layout
Return the layout of the given Bigarray.
valchange_layout : ('a,'b,'c)t->'dBigarray.layout->('a,'b,'d)tArray3.change_layoutalayout returns a Bigarray with the specified layout , sharing the data with a (and
hence having the same dimensions as a ). No copying of elements is involved: the new array and the
original array share the same storage space. The dimensions are reversed, such that getv[|a;b;c|]
in C layout becomes getv[|c+1;b+1;a+1|] in Fortran layout.
Since 4.06
valsize_in_bytes : ('a,'b,'c)t->intsize_in_bytesa is the number of elements in a multiplied by a 's Bigarray.kind_size_in_bytes .
Since 4.03
valget : ('a,'b,'c)t->int->int->int->'aArray3.getaxyz , 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.
valset : ('a,'b,'c)t->int->int->int->'a->unitArray3.setaxyv , 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.
valsub_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 Bigarray by restricting the first
dimension. See Bigarray.Genarray.sub_left for more details. Array3.sub_left applies only to arrays with
C layout.
valsub_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 Bigarray by restricting the second
dimension. See Bigarray.Genarray.sub_right for more details. Array3.sub_right applies only to arrays
with Fortran layout.
valslice_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 Bigarray 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.
valslice_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 Bigarray 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.
valslice_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 Bigarray 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.
valslice_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 Bigarray 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.
valblit : ('a,'b,'c)t->('a,'b,'c)t->unit
Copy the first Bigarray to the second Bigarray. See Bigarray.Genarray.blit for more details.
valfill : ('a,'b,'c)t->'a->unit
Fill the given Bigarray with the given value. See Bigarray.Genarray.fill for more details.
valof_array : ('a,'b)Bigarray.kind->'cBigarray.layout->'aarrayarrayarray->('a,'b,'c)t
Build a three-dimensional Bigarray initialized from the given array of arrays of arrays.
valunsafe_get : ('a,'b,'c)t->int->int->int->'a
Like Bigarray.Array3.get , but bounds checking is not always performed.
valunsafe_set : ('a,'b,'c)t->int->int->int->'a->unit
Like Bigarray.Array3.set , but bounds checking is not always performed.
