 This was with a large CSV loaded via the kmeans executable, profiled using
 valgrind's massif tool.

 This isn't a big problem for small matrices, but when it uses several GB
 of memory...

 One possibility: https://en.wikipedia.org/wiki/In-
 place_matrix_transposition

 Another might be to modify the way Armadillo loads files?
