Description

Read and write matrices as ASCII text files.

The file format is like:

     MATRIX                  -- header
     100 100                 -- width and height
     1.23 1.56 1.23 ...      -- data, separated by whitespace
     ....

Synopsis

Documentation

readMatrixFromTextFile :: (Num e, Read e, Unbox e) => FilePath -> IO (Array U DIM2 e) #

Read a matrix 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.

writeMatrixToTextFile :: (Show e, Source r e) => FilePath -> Array r DIM2 e -> IO () #

Write a matrix as a text file.
