6.1.1 Special variables

Special Variable: *array-element-print-format* ¶

The format control string used to print the elements of DENSE-ARRAYS:ARRAY.

It is possible to set this value to "~/USER-DEFINED-FUNCTION/" where USER-DEFINED-FUNCTION should accept at least four arguments.

Also see:
- https://en.wikipedia.org/wiki/Format_(Common_Lisp)
- http://www.gigamonkeys.com/book/a-few-format-recipes.html

Package

dense-arrays.

Source

dense-arrays.lisp.

Special Variable: *array-element-type* ¶

If BOUND, this is the default value of the ELEMENT-TYPE or TYPE argument. Overrides *ARRAY-ELEMENT-TYPE-ALIST*.
Is overriden by explicitly passing an ELEMENT-TYPE or TYPE argument.

Package

dense-arrays.

Source

package.lisp.

Special Variable: *array-element-type-alist* ¶

An ALIST mapping package to the default element-type used in that package. (Inspired from SWANK:*READTABLE-ALIST*)
Overrides none.
Is overriden by *ARRAY-ELEMENT-TYPE* when bound, or by explicitly passing an ELEMENT-TYPE or TYPE argument.

Package

dense-arrays.

Source

package.lisp.

Special Variable: *array-layout* ¶

Specifies the default layout constructed by DENSE-ARRAYS:MAKE-ARRAY and constructor functions like ASARRAY, ZEROS, ONES, etc in the DENSE-ARRAYS-PLUS-LITE package.

Package

dense-arrays.

Source

package.lisp.

Special Variable: *dense-array-class* ¶

Specifies the default value of CLASS in DENSE-ARRAYS:MAKE-ARRAY and other functions. (TODO: Specify these other functions.)

Package

dense-arrays.

Source

protocol.lisp.

---

6.1.2 Macros

Macro: do-arrays (rank/bindings &body body) ¶

Traverses the arrays in row-major order.

If the first argument RANK/BINDINGS is of type SIZE, it’d be treated as the rank of the arrays. Then, the BINDINGS are assumed to be the first element of the BODY.

Otherwise, the first argument is treated as if they are BINDINGS.
Each BINDING is of the form
(ELT-VAR ARRAY &OPTIONAL (ELEMENT-TYPE *) &KEY (CLASS-NAME *DENSE-ARRAY-CLASS*)) Here, only ARRAY is evaluated.

Examples

(let ((a (make-array ’(2 3)))
(b (make-array ’(2 3))))
(do-arrays ((c a t)
(d b t))
(print (list c d))))

(let ((a (make-array ’(2 3)))
(b (make-array ’(2 3))))
(do-arrays 2 ((c a t) ; The 2 indicates the rank of the arrays
(d b t))
(print (list c d))))

Either of the two cases might be faster depending on the number of dimensions.

6.1.4 Ordinary functions

Function: aref* (dense-array &rest subscripts) ¶

Accessor function for DENSE-ARRAYS::DENSE-ARRAY with semantics
intended to be similar to numpy’s indexing semantics.
See https://numpy.org/doc/stable/user/basics.indexing.html

Each element of SUBSCRIPTS can be
- either an integer denoting the position within the axis which is to be indexed
- or a list of the form (&OPTIONAL START &KEY END STEP) with each of START END STEP being integers if supplied. START denotes the start position within the axis, END denotes the ending position within the axis, STEP denotes at what distance within the axis the next element should come after the previous, starting from START

Each of the SUBSCRIPTS, START, END, STEP can also be negative integers, in which case the last element along the axis is given the index -1, the second last is given the index -2 and so on. Thus, ‘(aref ... ’(-1 :step -1))‘ can reverse a one dimensional array.

Like, CL:AREF or ABSTRACT-ARRAYS:AREF, returns the element corresponding to SUBSCRIPTS if all the subscripts are integers and there as many subscripts
as the rank of the array.

If the number (aka length) of SUBSCRIPTS were less than the array’s rank, or
if some of the SUBSCRIPTS were lists described above, then returns a VIEW
of the arrays. A VIEW is a window into the original array and thus
avoids copying the elements of the original array.

Examples illustrating the numpy-equivalent indexes:

a[::] (aref a nil)
a[::2] (aref a ’(0 :step 2))
a[3, ::-1] (aref a 3 ’(-1 :step -1))
a[3::, -1] (aref a ’(3) -1)

The SUBSCRIPTS can also be integer or boolean arrays, denoting which elements
to select from each of the axes. But in this case the corresponding elements
of the array are copied over into a new array.

Function: array-displacement (array) ¶

Returns two values:
- ARRAY-STORAGE
- and OFFSET along first axis
Consequences are undefined if ARRAY is displaced along multiple axis.

Package

dense-arrays.

Source

dense-arrays.lisp.

Function: array-layout (array) ¶

Package

Source

Function: array-offset (array axis-number) ¶

Return the length of offset corresponding to AXIS-NUMBER of ARRAY.

Package

dense-arrays.

Source

dense-arrays.lisp.

Function: array-offsets (array) ¶

Package

dense-arrays.

Source

dense-arrays.lisp.

Function: array-stride (array axis-number) ¶

Package

dense-arrays.

Source

dense-arrays.lisp.

Function: array-strides (array) ¶

Package

dense-arrays.

Source

dense-arrays.lisp.

Function: array= (array1 array2 &key test) ¶

Returns non-NIL if each element of ARRAY1 is equal to each corresponding element of ARRAY2 using TEST, which should be a two-argument function that takes the one element of the first array and the corresponding element of the second and tests for their equality.

Package

dense-arrays.

Source

aref.lisp.

Function: broadcast-array (array broadcast-dimensions) ¶

Package

dense-arrays.

Source

broadcast.lisp.

Function: broadcast-arrays (&rest arrays) ¶

Returns two values. The first value is the list of broadcasted arrays if the second value is non-NIL.

Package

dense-arrays.

Source

broadcast.lisp.

Function: broadcast-compatible-p (&rest arrays) ¶

Returns two values:
- The first value is a generalized boolean indicating whether the arrays can be broadcasted. - The second value is the dimension of the array resulting from the broadcast.

The broadcasting semantics are equivalent to numpy semantics. Two arrays are broadcast compatible, if
- they have the same dimensions, or
- if, for the dimensions they differ, one of the dimension is of length 1, or
- the dimensions of the lower-ranked array matches the rightmost dimensions
of the higher-ranked array

Thus, arrays with the following dimensions are broadcast-compatible:
- (3) (3)
- (3 1) (3 3)
- (3 3) (1 3)
- (3 3) (3)

Arrays with the following dimensions are not compatible:
- (3 1) (3)

See https://numpy.org/doc/stable/user/basics.broadcasting.html for an elaborate discussion.

Package

dense-arrays.

Source

broadcast.lisp.

Function: copy-array (array &key layout) ¶

Returns a copy of ARRAY. Creates a completely new array even if ARRAY is a VIEW (see ARRAY-VIEW-P).

Package

dense-arrays.

copy.lisp.

Package

dense-arrays.

Source

misc.lisp.

Function: make-array (dimensions &rest args &key element-type initial-element initial-contents constructor strides adjustable fill-pointer class layout displaced-to offsets displaced-index-offset) ¶

Like CL:MAKE-ARRAY but returns a DENSE-ARRAYS::DENSE-ARRAY instead of CL:ARRAY. Additionally takes

- LAYOUT argument which can be one of (:ROW-MAJOR :COLUMN-MAJOR NIL)
- CLASS argument which should be a class designator denoting the class to which the constructed dense array will belong to

- CONSTRUCTOR if supplied should be a function that takes as many arguments
as the number of dimensions aka rank of the array, and return the element that should correspond to the position indicated by the arguments of the function. For example:

(make-array ’(2 3) :constructor (lambda (&rest indexes) (cons ’indexes indexes))) ;=> #<STANDARD-DENSE-ARRAY :ROW-MAJOR 2x3 T
((INDEXES 0 0) (INDEXES 0 1) (INDEXES 0 2))
((INDEXES 1 0) (INDEXES 1 1) (INDEXES 1 2))
{10194A2FE3}>

6.1.5 Generic functions

Generic Function: storage-accessor (class) ¶

Returns a SYMBOL that is fbound to an accessor function that takes (STORAGE INDEX) as arguments and returns the element at INDEX in STORAGE. The function is an accessor function in the sense that SYMBOL should also be associated with (SETF SYMBOL) function that takes (NEW-VALUE STORAGE INDEX) as arguments and sets the STORAGE element at INDEX to NEW-VALUE.
This function is primarily used inside AREF, ROW-MAJOR-AREF and DO-ARRAYS, and their SETF counterparts.

Generic Function: storage-allocator (class) ¶

Generic Function: storage-deallocator (class) ¶

The upgraded array element type is then stored in the dense-array object and used for other tasks downstream.
