Readme for matrix-market-attoparsec-0.1.0.1
[back to package description]matrix-market-attoparsec
Attoparsec parser for the NIST Matrix Market format [1].
The library also contains functions for serializing to text file, and the read/write/read roundtrip works as expected.
User guide
The module Data.Matrix.MatrixMarket exports the user interface:
readMatrix :: FilePath -> IO (Matrix S.Scientific)
readArray :: FilePath -> IO (Array S.Scientific)
writeMatrix :: Show a => FilePath -> Matrix a -> IO ()
writeArray :: Show a => FilePath -> Array a -> IO ()
The first two functions contain the parsing logic, and make use of scientific for parsing numerical data in scientific notation.
test/LibSpec.hs contains a simple read/write/read sanity test:
m0 <- readMatrix fname -- load original
writeMatrix ftemp m0 -- save as temp
m1 <- readMatrix ftemp -- load temp
m0 `shouldBe` m1 -- compare temp with original
