the class Matrix method factory.

public static Matrix factory(Path path) throws EvaluationException {
    try (BufferedReader reader = Files.newBufferedReader(path)) {
        char[] buffer = new char[10];
        reader.mark(buffer.length + 1);
        // just assume buffer is filled completely
        reader.read(buffer);
        String line = new String(buffer);
        reader.reset();
        if (line.toLowerCase().startsWith("sparse"))
            return new MatrixSparse(reader);
        // TODO: import Matlab format.
        return new MatrixDense(reader);
    } catch (IOException exception) {
        throw new EvaluationException("Can't open matrix file");
    }
