Alberto Ruiz has developed a linear algebra library which could be seen as an alternative to Matlab/Octave, using the GSL, ATLAS, LAPACK, etc. IIRC. http://dis.um.es/~alberto/GSLHaskell/ I've optimized it in some places, and added an interface which guarantees operand conformability through the t

I have tried.  Using just normal lists, I found it difficult to avoid huge space leaks, but once things are working, the end result is easy to reason about.I'm considering giving it another try using Stream Processors or some form of Arrows instead of lists.  I think this strategy might allow me to

Is anyone using Haskell for heavy numerical computations? Could you share your experience? My app will be mostly about running computations over huge amounts of stock data (time series) so I'm thinking I might be better of with OCaml. Thanks, Joel -- http://wagerlabs.com/ _
