Numerical-Routines-in-Haskell

Here is a collection of simple Haskell programs that could be a help to people learning Haskell. I recommend the following books for learning Haskell:

• Learn You a Haskell for Great Good! by Miran Lipovaca
• Learn Physics with Functional Programming by Scott N. Walck

Important: You have to use ghci to run these programs. Do like so:

$ ghci                         
GHCi, version 9.2.4: https://www.haskell.org/ghc/  :? for help
ghci> :load simpsonsRule.hs
[1 of 1] Compiling Main             ( simpsonsRule.hs, interpreted )
Ok, one module loaded.
ghci> integral 0.1 cos 0 pi

Some of the linear algebra routines require packages from cabal. Cabal: Common Architecture for Building Applications and Libraries

First, you have to have cabal-install installed on your OpenBSD or Linux computer.

Once cabal-install is installed, do this in your user account:

$ cabal update

$ cabal install matrix

$ cabal install --lib matrix
