R has numerical values up to about 1e308 (10^308), but you have not told us your matrix size. It sounds as if you would benefit from re-scaling your matrix and problem. > I need a numerical value for determinant, can somebody tell me what > should I do? Read the help page (as the posting guide asked you to)? It mentions determinant() which will give you the value on log scale. > > Kalin > > Paul Smith <[EMAIL PROTECTED]> wrote: On Nov 16, 2007 7:27 PM, kalin lagno > wrote: >> Which R function I should use to obtain determinant of a matrix with >> real(and complex) numbers? > > For real matrices: > > ?det > > Paul > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > > > > --------------------------------- > Never miss a thing.
