Something seems wrong here. Above '.' was parsed as an infix type
variable. As
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
