Long Description

The array-operations system is a collection of functions and macros for manipulating Common Lisp arrays and performing numerical calculations with them.

Array-operations is a ’generic’ way of operating on array like data structures using a syntax that is natural for Common Lisp. Several aops functions have been implemented for data-frame. For those that haven’t, you can transform arrays to data frames using the df:matrix-df function, and a data-frame to an array using df:as-array. This make it convenient to work with the data sets using either system.

3.3 array-operations/all

This top level package re-exports the individual packages: generic, reducing, matrices, creating, indexing, displacing, transforming and stacking. It does not export utilities. The reason for this structure is the use of the ASDF package-inferred-system, where each file is its own package. None of Papp’s other libraries use this, and it seems to have been added after he abandoned the library.

4.1 Public Interface


4.1.1 Macros

Macro: &dims (&rest dimensions)

Dimensions of array-like object.

Package

array-operations/generic.

Source

file-type.lisp.

Macro: each-index (index &body body)

Given one or more symbols INDEX, walks the BODY expression to determine the index ranges by looking for AREF and ROW-MAJOR-AREF calls.

Transpose of 2D array A

(each-index (i j)
(aref A j i))

Diagonal of a square 2D array

(each-index i (aref A i i))

Turn a 2D array into an array of arrays

(each-index i
(each-index j
(aref A i j)))

Matrix-vector product:

(each-index i
(sum-index j
(* (aref A i j) (aref x j))))

Package

array-operations/indexing.

Source

file-type.lisp.

Macro: each-index! (array index &body body)

Sets elements of the given ARRAY to values of the BODY, evaluated at array indices INDEX

Note: This has the same semantics as each-index and each-index*,
but the INDEX ranges are taken from the ARRAY dimensions, not
a code walker.

Package

array-operations/indexing.

Source

file-type.lisp.

Macro: each-index* (element-type index &body body)

Given one or more symbols INDEX, creates an array with ELEMENT-TYPE, then iterates over the index ranges with the innermost loop using the last index. Each iteration evaluates BODY, and sets the array element.

To find the range of the indices, walks the BODY expression
to determine the index ranges by looking for
AREF and ROW-MAJOR-AREF calls.

Transpose of 2D array A

(each-index* t (i j)
(aref A j i))

Diagonal of a square 2D array

(each-index* t i (aref A i i))

Turn a 2D array into an array of arrays

(each-index* t i
(each-index* t j
(aref A i j)))

Outer product of two 1D arrays to create a 2D array

(each-index* t (i j)
(* (aref x i) (aref y j)))

Matrix-vector product:

(each-index* t i
(sum-index j
(* (aref A i j) (aref x j))))

Package

array-operations/indexing.

Source

file-type.lisp.

Macro: multf (place &rest values)

Multiply by the arguments

Package

array-operations/utilities.

Source

file-type.lisp.

Macro: nested-loop (syms dimensions &body body)

Iterates over a multidimensional range of indices.

SYMS must be a list of symbols, with the first symbol corresponding to the outermost loop.

DIMENSIONS will be evaluated, and must be a list of dimension sizes, of the same length as SYMS.

Example:
(nested-loop (i j) ’(10 20) (format t ’~a ~a~%’ i j))

expands to:

; Check dimensions
(destructuring-bind (g1 g2) ’(10 20)
(loop for i from 0 below g1 do
(loop for j from 0 below g2 do
(format t ’~a ~a~%’ i j))))

with some additional type and dimension checks.

Package

array-operations/utilities.

Source

file-type.lisp.

Macro: reduce-index (function index &body body)

Reduction over one or more INDEX symbols in an array expression.
The range of these symbols is determined by walking the tree
for AREF and ROW-MAJOR-AREF calls.

Example:

(defparameter A #2A((1 2) (3 4)))

(reduce-index #’+ i (row-major-aref A i)) ; Sum all elements (sum-index) => 10

(reduce-index #’* (i j) (aref A i j)) ; Multiply all elements
=> 24

(reduce-index #’max i (row-major-aref A i)) ; Maxmum value

Example:

(defparameter A #2A((1 2) (3 4)))

(sum-index i (row-major-aref A i)) ; Sum all elements => 10

(sum-index (i j) (aref A i j)) ; Sum all elements
=> 10

(sum-index i (aref A i i)) ; Trace of array
=> 5

Package

array-operations/indexing.

Source

file-type.lisp.

Macro: vectorize (variables &body body)

Makes a new array of type ELEMENT-TYPE, containing the result of an array expression. All input and outputs have the same shape, and BODY is evaluated for each index

VARIABLES must be a list of symbols bound to arrays.
Each array must have the same dimensions. These are
checked at compile and run-time respectively.

(let ((a #2A((1 2) (3 4))))
(vectorize (a) (+ a 1)))

to elements of ARRAY, to find the ’best’. The row-major-aref index is returned.

4.1.3 Generic functions

Generic Function: as-array (object)

Return the contents of OBJECT as an array. Exact semantics depends on OBJECT, but generally objects which contain elements in a rectilinear coordinate system should have a natural mapping to arrays.

When the second value is T, the array itself does not share structure with OBJECT, but its elements may. Otherwise, it is indeterminate whether the two objects share structure, and consequences of modifying the result are not defined. Methods are encouraged but not required to return a second value.

Package

array-operations/generic.

Source

file-type.lisp.

Methods
Method: as-array ((array array))
Method: as-array (object)
Generic Function: dim (array axis)

Return specificed dimension of ARRAY.

Package

array-operations/generic.

Source

file-type.lisp.

Methods
Method: dim ((array array) axis)
Method: dim (array axis)
Generic Function: dims (array)

Return a list of dimensions.

For non-array objects, SIZE, DIM, NROW and NCOL use this method by default, so it is enough to define it (unless efficiency is a concern).

When DIMS is not defined for an object, it falls back to as-array, which may be very inefficient for objects which need to be consed. It is always advisable to define DIMS.

Package

array-operations/generic.

Source

file-type.lisp.

Methods
Method: dims ((array array))
Method: dims (array)
Generic Function: element-type (array)

Return TYPE such that

1. all elements of ARRAY are guaranteed to be a subtype of TYPE,

2. if applicable, elements of ARRAY can be set to values which are of a type that is a subtype of TYPE.

Methods
Method: size ((array array))
Method: size (array)
Generic Function: stack-cols-copy (source destination element-type start-col)

Method used to implement the copying of objects in STACK-COL*, by copying the elements of SOURCE to DESTINATION, starting with the column index START-COL in the latter. Elements are coerced to ELEMENT-TYPE.

This method is only called when (DIMS SOURCE) was non-nil. It is assumed that it only changes elements in DESTINATION which are supposed to be copies of SOURCE. DESTINATION is always a matrix with element-type upgraded from ELEMENT-TYPE, and its NROW should match the relevant dimension of SOURCE.

All objects have a fallback method, defined using AS-ARRAY. The only reason for defining a method is efficiency.

Methods
Method: stack-cols-copy (source destination element-type start-col)
