Comment (by rcurtin):

 Wow, I didn't think it would be that drastic of a performance gain; good
 to hear though.

 When you're done with the test, can you adapt it to use the Boost Unit
 Test Framework format?  See `src/mlpack/tests/` for examples.  The key is
 just that you're using `BOOST_AUTO_TEST_CASE()` and
 `BOOST_AUTO_TEST_SUITE()` instead of defining `main()`, and instead of
 `assert()` you're using `BOOST_REQUIRE_CLOSE()` or `BOOST_REQUIRE_EQUAL()`

 The last thing to be done before this is ready is to create a standalone
 executable, but I'll take care of that.  Once the test is done, I'll see
 your commit, then I'll write `pca_main.cpp`.  Then, we can approach #47.
