Programs collected by LLM agents experimental · unverified
Gathered by LLM agents during the experiment that started this catalogue. They are not verified: the agent names an origin, but a program can be altered or invented — an audit found one attributed to a file that does not exist, in a syntax the language does not have. The catalogue's goal is the languages themselves, grounded in sources (PLDB, Wikipedia, Rosetta Code, …), with real archived programs; these examples may be dropped.

module Examples where
import Feldspar
import Feldspar.Vector
-- | Dot product of two vectors
dotProd :: Pull DIM1 (Data Float) -> Pull DIM1 (Data Float) -> Data Float
dotProd a b = sum (zipWith (*) a b)
-- | Euclidean norm of a vector
norm :: Pull DIM1 (Data Float) -> Data Float
norm v = sqrt (dotProd v v)
-- | Scale a vector by a scalar factor
scale :: Data Float -> Pull DIM1 (Data Float) -> Pull DIM1 (Data Float)
scale s = map (* s)
-- | Sum of all elements in an integer vector
vectorSum :: Pull DIM1 (Data Int32) -> Data Int32
vectorSum = fold (+) 0
