Here is a copy of version 0.7b of Laurens van der Maaten's Matlab Toolbox for Dimensionality Reduction.
I was unable to access Mr. van der Maarten's
site and found a comment at
Nuit Blanche's blog confirming the issue. The license allows
for redistribution non-commercially, as you can see in the file's
included Readme.txt
. If there is a newer version,
please let me know. My email is my username at cmu.
