repa-io- Read and write Repa arrays in various formats.

Safe HaskellSafe-Infered



Read and write vectors as ASCII text files.

The file format is like:

	VECTOR			-- header
	100			-- length of vector
	1.23 1.56 1.23 ...	-- data, separated by whitespace



readVectorFromTextFile :: (Num e, Read e, Unbox e) => FilePath -> IO (Array U DIM1 e)Source

Read a vector from a text file.

  • WARNING: This is implemented fairly naively, just using Strings under the covers. It will be slow for large data files.
  • It also doesn't do graceful error handling. If the file has the wrong format you'll get a confusing error.

writeVectorToTextFile :: (Show e, Repr r e) => Array r DIM1 e -> FilePath -> IO ()Source

Write a vector as a text file.
