If you’re crossproding X by itself, I think passing symmetric = TRUE to
eigen will eke out more speed.

Rather than the full SVD of
Good day,
I have a real scenario involving 45 million biological cells (samples) and 60
proteins (variables) which leads to a segmentation fault for svd. I thought
this might be a good example of why it might benefit from a long vector upgrade.
test <- matrix(rnorm(4500*60), ncol = 60)
test
