Description

Simple multidimensional array with useful numeric instances.

Contractions only require equal dimension.

type Array t = NArray None tSource
Multidimensional array with unespecified coordinate type.
listArraySource
:: Coord t
=> [Int]dimensions
-> [t]elements
-> Array t
Construction of an Array from a list of dimensions and a list of elements in left to right order.
scalar :: Coord t => t -> NArray i tSource
Create a 0-dimensional structure.
index :: Coord t => Name -> [Array t] -> Array tSource
Create an Array from a list of parts (index = newIndex None).
(!) :: (Compat i, Coord t) => NArray i t -> [Char] -> NArray i tSource
Rename indices in alphabetical order (renameO) using single letter names.
(!>) :: (Compat i, Coord t) => NArray i t -> [Char] -> NArray i tSource

Explicit renaming of single letter index names.

For instance, t >@> "pi qj" changes index "p" to "i" and "q" to "j".

(~>) :: Coord t => NArray i t -> String -> NArray i tSource

reorder (transpose) dimensions of the array (with single letter names).

Operations are defined by named indices, so the transposed array is operationally equivalent to the original one.

(.*) :: (Coord a, Compat i) => NArray i a -> NArray i a -> NArray i aSource
Element by element product.
printA :: (Coord t, Compat i, PrintfArg t) => String -> NArray i t -> IO ()Source
Print the array as a nested table with the desired format (e.g. %7.2f) (see also formatArray, and formatScaled).
