I am using MKL with R 4.5.0 on Linux, and eigen() is producing different results with identical calls. Specifically, when I run the code below, I get "FALSE" from identical(). Just in case it had something to do with a random number generator, I put identical set.seed() calls immediately before each eigen() call, but that did not help. Has anyone seen this behavior before?
(When n is 5, the identical() call almost always returns "TRUE". As n increases, the proportion of FALSE results increases, and it is nearly always FALSE when n is 50.) Jesse *** n <- 50 set.seed(20250504) Sigma <- rWishart(1, df = n, Sigma = diag(n))[,,1] e1 <- eigen(Sigma) e2 <- eigen(Sigma) identical(e1, e2) ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide https://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
