/* * @name DMatrixSlice output stream function.
*
* This is a function that are used to output a DMatrixSlice object
* to a char based output stream. This format is ment to be both
* human and machine readable. In fact the \Ref{input} function
* can be used to read in the output produced by this function.
* This function is ment to be the machinary for an optional output stream
* operator \Ref{operator<<}.
*
* The output format is diferent depending on the on whether the
* bits #LinAlgPackIO::ignore_dim_bit# and #LinAlgPackIO::no_insert_newlines_bit# are set.
* The default output format is (exta_flags == 0):
*
* #gms.rows() gms.cols()#\\
* #gms(1,1) gms(1,2) gms(1,3) ... gms(1,gms.cols())#\\
* #gms(2,1) gms(2,2) gms(2,3) ... gms(2,gms.cols())#\\
* # . . . .#\\
* #gms(gms.rows(),1) gms(gms.rows(),2) gms(gms.rows(),3) gms(gms.rows(),gms.cols())#\\
*
* If #extra_flags & LinAlgPackIO::ignore_dim_bit != 0# then the dimensions of the
* matrix are not output and if #extra_flags & LinAlgPackIO::no_insert_newlines_bit != 0#
* then newline char ('\n') are not inserted after each row.
*
* Each of the elements are are put into columns according to the width set in the
* output stream #os# when it is called and other formating commands. Even if the set
* width is 0 or less than
* the number of char's for the element a space ' ' will be inserted between them.
* The elements are formated according to the format in the stream #os#.
*
* If #gms.rows() == 0# then no elements will be output and if
* #extra_flags & LinAlgPackIO::ignore_dim_bit != 0# and only the operation
* #os << gms.rows() << ' ' << gms.cols() << endl;# will be performed.
*
* If any of the output operations fails then a #std::ios_base::failure# exception is thrown.
