Inserts a Window into a delayed array while scaling the window down if it doesn't fit inside that array.

Since: 0.3.0

getWindow :: Array DW ix e -> Maybe (Window ix e)

Get the Window from a windowed array.

Since: 0.2.1

dropWindow :: Array DW ix e -> Array D ix e

Drop the Window from a windowed array.

Since: 0.3.0

makeWindowedArray

Arguments

:: Source r ix e

=> Array r ix e

Source array that will have a window inserted into it

-> ix

Start index for the window

-> Sz ix

Size of the window

-> (ix -> e)

Indexing function foto use inside window

-> Array DW ix e

Construct a delayed windowed array by supply a separate element producing function for the interior of an array. This is very usful for stencil mapping, where interior function does not perform boundary checks, thus significantly speeding up computation process.
