[Haskell-cafe] writing a function to make a correspondance between type-level integers and value-level integers
I'm late to this discussion and must have missed the motivation for it. Specifically, how is your goal, vector/tensor operations that are statically assured well-dimensioned differs from general well-dimensioned linear algebra, for which several solutions have been already offered. For example, the Vectro library has been described back in 2006: http://ofb.net/~frederik/vectro/draft-r2.pdf http://ofb.net/~frederik/vectro/ The paper also talks about reifying type-level integers to value-level integers, and reflecting them back. Recent GHC extensions (like DataKinds) make the code much prettier but don't fundamentally change the game. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Third. I really like the hands on approach.

Certainly less entertaining but depending on your public, this one with FP Complete's Aaron Contorer can be valuable: http://www.youtube.com/watch?v=Fqi0Xu2Enaw 2013/6/17 Mihai Maruseac > Hi, > > I was wondering if we have similar movies for Haskell as > https://www.youtube.com/watch?v=kLO1djacsfg and > https://www.youtube.com/watch?v=E3418SeWZfQ exist for Java. > > I indend to give them to some people to make them intrigued by the > language and start learning it / looking for it. > > -- > MM > "All we have to decide is what we do with the time that is given to us" > > ___ > Haskell-Cafe mailing list > Haskell-Cafe@haskell.org > http://www.haskell.org/mailman/listinfo/haskell-cafe > ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Hi, I was wondering if we have similar movies for Haskell as https://www.youtube.com/watch?v=kLO1djacsfg and https://www.youtube.com/watch?v=E3418SeWZfQ exist for Java. I indend to give them to some people to make them intrigued by the language and start learning it / looking for it. -- MM "All we have to decide is what we do with the time that is given to us" ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
