Hey guys,
thanks for the very quick help. The code works and looks like: (any tips regards speed and memory usage ?) import System.IO import Data.Array import Data.Packed.Matrix
parse :: String -> [[Double]] -- expects plainer syntax parse = map (map read . words) . lines
main = do -- read and show plain text text<- readFile "./log.txt" putStrLn text
-- read and show parsed list of lists putStrLn "parsed list of lists" let m = parse text putStrLn (show m)
-- convert to matrix and show let a = fromLists m putStrLn (show a)
-- cuts out first row to get signal let t = takeColumns 1 a putStrLn (show t)
putStrLn "Finish"
