I am planning to write a program that performs MDS. Any pointers to where I can access the pseudo-code for MDS? Thanks!
There are different kind of MDS (e.g., see this brief review). Here are two pointers:
You can also look for "Manifold learning" which should give you a lot of techniques for dimension reduction (Isomap, PCA, MDS, etc.); the term was coined by the Machine Learning community, among others, and they probably have a different view on MDS compared to psychometricians.
If you have the Statistics Toolbox in MATLAB you can read the source code of
In MATLAB you can type
and that will open up an editor window that shows you the
