Documentation
class Eq sh => Shape sh where Source
Class of types that can be used as array shapes and indices.
Methods
Get the number of dimensions in a shape.
The shape of an array of size zero, with a particular dimensionality.
The shape of an array with size one, with a particular dimensionality.
intersectDim :: sh -> sh -> sh Source
Compute the intersection of two shapes.
addDim :: sh -> sh -> sh Source
Add the coordinates of two shapes componentwise
Get the total number of elements in an array with this shape.
sizeIsValid :: sh -> Bool Source
Check whether this shape is small enough so that its flat
indices an be represented as Int. If this returns False then your
array is too big. Mostly used for writing QuickCheck tests.
Arguments
| :: sh | Shape of the array. |
| -> sh | Index into the array. |
| -> Int |
Convert an index into its equivalent flat, linear, row-major version.
Arguments
| :: sh | Shape of the array. |
| -> Int | Index into linear representation. |
| -> sh |
Inverse of toIndex.
Arguments
| :: sh | Start index for range. |
| -> sh | Final index for range. |
| -> sh | Index to check for. |
| -> Bool |
Check whether an index is within a given shape.
listOfShape :: sh -> [Int] Source
Convert a shape into its list of dimensions.
shapeOfList :: [Int] -> sh Source
Convert a list of dimensions to a shape
deepSeq :: sh -> a -> a infixr 0 Source
Ensure that a shape is completely evaluated.
Check whether an index is a part of a given shape.
