Documentation
array :: Type a => Size a -> a -> Data a
Like value but with an extra Size argument that can be used to increase
the size beyond the given data.
Example 1:
array (10 :> 20 :> universal) [] :: Data [[DefaultInt]]
gives an uninitialized 10x20 array of DefaultInt elements.
Example 2:
array (10 :> 20 :> universal) [[1,2,3]] :: Data [[DefaultInt]]
gives a 10x20 array whose first row is initialized to [1,2,3].
function :: (Syntactic a, Type b) => Bool -> String -> (Info a -> Size b) -> (Internal a -> b) -> a -> Data b
function2 :: (Type a, Type b, Type c) => String -> (Size a -> Size b -> Size c) -> (a -> b -> c) -> Data a -> Data b -> Data c
Identical to condition. Provided for backwards-compatibility, but will be
removed in the future.
parallel'' :: Type a => Bool -> Data Length -> (Data Index -> Data a) -> Data [a] -> Data [a]
Parallel array with continuation
parallel' :: Type a => Data Length -> (Data Index -> Data a) -> Data [a] -> Data [a]
Parallel array with continuation
Arguments
| :: Type a | |
| => Data Length | Length of resulting array (outermost level) |
| -> (Data Index -> Data a) | Function that maps each index in the range |
| -> Data [a] |
Parallel array
Since there are no dependencies between the elements, the compiler is free to compute the elements in any order, or even in parallel.
Arguments
| :: Syntactic st | |
| => Data Length | Number of iterations |
| -> st | Initial state |
| -> (Data Index -> st -> st) | Loop body (current index and state to next state) |
| -> st | Final state |
For loop
