This is Fortran archive package of Non-metric Multidimensional
Scaling Method (NMDS) developed by Y-h. Taguchi and Y. Oono.
Ver. 1.3.1

For installation, see INSTALL.
For instruction, see INSTRUCTION.
For differences between versions, see CHANGELOG

The construction of this package is as follows:

MDS_final : directory includes Fortran source codes
MDS_final/utilities : directory includes utilities
MDS_final/distcal1 : directory includes example of distcal1.f
MDS_final/doc : some technical details

Contents of MDS_final :
  README : This file.
  INSTALL : installation how to.
  INSTRUCTION : brief instruction of this package.
  Makefile : is Makefile
  mds.f : main routine.
  mds-cgi.f : main routine for output of geomview format
  
  Subroutines
    distcal.f : compute distance matrix of obtained configuration.
    distcal1.f : compute distance matrix of target configuration.
      (In this package, it reads d dimensional vector from file fort.51.
      Modify it as you like) It is same as distcal1/distcal1_vec.f.
    fcal.f : compute 'Force' along bonds.
    init.f : initialization.
    prep.f : compute rank order data for targeted configuration.
    renorm.f : centered and normalize vector.
    test.f : compute significant level for obtained configuration.
    geomview_out.f : output geomview format of obtained config.

    rand.f: uniform random number generator form SLATEC (*)
    
    spsort.f : quick sort routine form SLATEC (*)
    Subroutines called by spsort.f itself or those called by spsort.f is
      as follows:
      fdump.f :
      i1mach.f : 
      j4save.f :
      xerhlt.f : 
      xercnt.f :
      xermsg.f :
      xerprn.f :
      xersve.f :
      xgetua.f :

Contents of MDS_final/utilities:
  Makefile : is Makefile
    ranvec.f : generate vectors whose components are random numbers
    hypercube.f : generate hypercube (3 dimensional)
    
Contents of MDS_final/distcal1 : 
   distcal1_vec.f : compute distance matrix of target configuration,
      d dimensional vector from file fort.51.

Content of MDS_final/doc : 
      README : some explanation
      paper.pdf : much more technical details (unpublished)

This package is tested on Kondara 2.0 (http://www.kondara.org),
which is one of major distribution of Linux.
It employs usual g77 compilers, thus this package would be
executed for any computer system with Fortran compiler.
