Hi,
Thanks to everyone who reviewed my code and submitted comments the
first time! I've updated the code and transitioned to using the State
monad. Perhaps controversially, I've continued to use | in a bunch
of places that the monad didn't get rid of because I think it's more
readable, but I'm

What about using () from Control.Arrow?

excellent idea. you can make diff for Data.Array.ST/IO and send it to the
libs

it's perfectly documented in module sources itself :) you can also
look at the ndpFlatten directory in ghc compiler's sources. i've
successfully used them in my program, of course this makes program
faster

The first line isn't needed, it does the same as the second line.

Hello, I am trying to write a haskell-native matrix library (providing a
similar set of functionality as gsl's matrix/eigenvector routines). I have had
a look at other attempts at matrix libraries, and have found Hal Daume's and
Alberto Ruiz's libraries to offer a good amount of functionality.

Thanks for the tip. A modified version of your suggestion worked for me:
unsafeFreezeMatrix :: MMatrix s - ST s Matrix
unsafeFreezeMatrix (MMatrix x1 x2 marray) = do block - unsafeFreeze marray
return $ Matrix x1 x2 block
However, just out of

You might want to look at the definition of Data.Array.ST
