Dear all, I want to read numeric data in vector / matrix format generated by octave. As I haven't seen any octave specific libraries yet (only matlab), I'm tyrying the way via ascii - file. The folloing file log.txt contains three signal traces in the three columns (time, signal 1, signal 2) 0 30 9 0.1 30 9 0.2 30 9 0.3 30 9 0.4 30 9 0.5 30 9 0.6000000000000001 30 9 0.7000000000000001 30 9 0.8 30 9 0.9 30 9 1 30 9 I got the following bit of code compiled with ghc: import System.IO main = do text <- readFile "./log.txt" putStrLn text putStrLn "SecondLot" let m = read text :: [[Double]] putStrLn (show m) putStrLn "Finish" Reading text works, but not reading text into m. The Output: 0 30 9 0.1 30 9 0.2 30 9 0.3 30 9 0.4 30 9 0.5 30 9 0.6000000000000001 30 9 0.7000000000000001 30 9 0.8 30 9 0.9 30 9 1 30 9 SecondLot signalImport: Prelude.read: no parse Any suggestions ? - Thanks in advance. -- View this message in context: http://haskell.1045720.n5.nabble.com/Data-import-from-octave-text-file-tp449...
