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.
