Also, why is whiten=TRUE the default value? This is IMHO super confusing, all other tsne libraries usually do not whiten by default, see e.g. Rtsne. When the data have some zero eigenvalues, whitening is not possible and your function with default whiten=TRUE does not work at all.

Why not change to whiten=FALSE by default?
