When I try to compile the attached file using

ghc +RTS -c -RTS -package javavm -c EigenvalueCalculatorHaskell.hs -o EigenvalueCalculatorHaskell.o

I get the error

EigenvalueCalculatorHaskell.hs:28: parse error on input `putStrLn'

Your code is using a mixture of explicit and implicit layout: your do-expressions have curly braces {...} and semicolons, but the let-expression on line 22 does not. I suggest adding the layout tokens to the let-expression to fix it. Cheers, Simon
