Multi-dimensional arrays

import NumHask.Array

imports the fixed version of Array and Shape

In many situations, where shape is being tracked or otherwise only known at runtime, a clear module arrangement is:

import NumHask.Array.Shape
import qualified NumHask.Array.Fixed as F
import qualified NumHask.Array.Dynamic as D

Arrays are higher-kinded numbers that can be indexed into with an [Int]. Higher-kinded numbers are things with a non-primitive type that we wish to use the usual numerical operators on: +,-,*,/,abs,tan and so on.

The design of numhask-array:

• allows shape to be specified at both the type and value level.
• provides operators at value and type level to help manipulate shapes.
• provides fixed and dynamic arrays with the same API.
