#+TITLE: Dinwiddy

N-dimensional arrays in Idris 2, featuring:

 * Nat-indexable n-dimensional array type synonyms

 * Matrices and matrix algebra helper functions

** Usage

At a very basic level, the API for an N-dimensional array in Dinwiddy is the following:

#+begin_src idris

Array : (dimension : Nat) -> (sizes : Vect dimension Nat) -> (type : Type)

#+end_src

For example, the following type declaration =x=:

#+begin_src idris

x : Array 2 [2, 3] Bool

#+end_src

Will create an array that looks like this:

#+begin_src

###

###

#+end_src

Full of booleans. It's value could be, for example:

#+begin_src idris

x = [[ True,  True,  True ],

     [ False, False, True ]]

#+end_src
