If you are interested in the Beta=1 TW distribution, not the Beta=2 TW distribution shown here, you can find it in MATLAB central by clicking on the "tracywidom" tag.
The TW1 distribution can be used to test for the number of significant principal components as described in: Patterson N, Price AL, Reich D, 2006 Population Structure and Eigenanalysis. PLoS Genet 2(12): e190. doi:10.1371/journal.pgen.0020190
