MDS for Mathematica 6.0

Thu, 21 Jun 2007 14:37:16 -0400

A few weeks ago someone asked for examples of the Multidimensional Scaling package for Mathematica. While I was at it, I updated the package to work with version 6.0 (and probably 5.2, but not tested). The old 4.x version remains here for those who need it.

Installation is simple, unpack the zip file and install in your system-wide or user Applications folder. (The examples assume the data is stored in the system-wide area, so you’ll need to tweak a few Import[]s if you put it somewhere else. The rest of the package should work perfectly fine however.)

Usage is pretty simple, there are basically two functions exported:

MultidimensionalScaling[data,dimensions] - takes the dissimilarity matrix data and creates a state for dimensions dimensions. The data structure basically consists of {Stim Configuration, SVD Data, SVD Data, Stress}
IterateMDS[state] or IterateMDS[state,times] - takes the state returned from MultidimensionalScaling[] and iterates it.

For examples, see the MDS Demo file in the Examples directory. That is all.

Of course you use Mathematica, we all do, it’s nothing to be ashamed of. If you find yourself editing the occasional .m file in BBEdit, this language module is for you.

Download Mathematica.plist

If you write the occasional MathLink program, this one will be useful also.

Download MathLinkTemplate.plist

Place them in ~/Library/Application Support/BBEdit/Language Modules and enjoy your color-filled goodness.

RenderMan RIB and Shading Language Language Modules for BBEdit

If you’re me, you use BBEdit occasionally.

You also use RenderMan.

If you use these things, these BBEdit language modules will be useful to you.

Download RendermanRIB.plist
Download RendermanShadingLanguage.plist

Place them in ~/Library/Application Support/BBEdit/Language Modules and enjoy your color-filled goodness.

MDS Package

A Mathematica package for performing multi-dimensional scaling calculations. Not well documented, if you use it, let me know and I can send some better examples than what are in the .m file.
