Hi all, when testing the new improvements in the new 1.7.0-version I stumbled over the following: >eigen(matrix(c(0,.3,2,.9),2,2)) Error in eigen(matrix(c(0,.3,2,.9),2,2)) : LAPACK routine DGEEV gave error code -13 >eigen(matrix(c(0,.3,2,.9),2,2),EISPACK=TRUE) $values [1] 1.3458236 -0.4458236 $vectors [,1] [,2] [1,] -1.1436890 -0.9760443 [2,] -0.7696018 0.2175718 My R-version [1] "R version 1.7.0, 2003-04-16", running on Debian PC. Anyone who has a c...

...ind the following Since ACML contains a full LAPACK, if selected as the BLAS it can be used as the LAPACK /via/ --with-lapack. If you do use --with-lapack, be aware of potential problems with bugs in the LAPACK 3.0 sources (or in the posted corrections to those sources). In particular, bugs in |DGEEV| and |DGESDD| have resulted in error messages such as DGEBRD gave error code -10 Not quite the same error code, but close enough I suspect they're related. I tried different forms of blas too (atlas, acml) - made little difference. So, several quick questions: 1. anyone managed to get x86...

Hi, I got an error message in my program saying "Error in eigen(gene_intersection.kernel) : error code 1 from Lapack routine 'dsyevr' Execution halted". As you see, I was trying to compute the eigenvalues of a matrix but got this error. Is there anyone who knows what this error means and how I can fix it? Theoretically the eigenvalues should be nonnegative, if it helps.

The help page for eigen says Source: By default ?eigen? uses the LAPACK routines ?DSYEVR?, ?DGEEV?, ?ZHEEV? and ?ZGEEV? LAPACK is from <URL: http://www.netlib.org/lapack> and its guide is listed in the references. You need to consult that guide and/or the source code: all I saw at a cursory look was *> \param[out] INFO *> \verbatim *> INFO is INTEGE...

I tried switching the method used in errorsarlm to "eigenw" but this also resulted in an e...

I noticed that there is some redundant text in eigen.Rd (both the patched and the devel version). "whereas" appears to be a leftover of previous versions. \source{ By default \code{eigen} uses the LAPACK routines \code{DSYEVR}, \code{DGEEV}, \code{ZHEEV} and \code{ZGEEV} whereas LAPACK is from \url{http://www.netlib.org/lapack} and its guide is listed in the references. } Berend

Dear all I am so glad the R can provide the efficient calculate about eigenvector and eigenvalue. However, i have some puzzle about the procedure of eigen. Fristly, what kind of procedue does the R utilize such that the eigen are obtained? For example, A=matrix(c(1,2,4,3),2,2) we can define the eigenvalue lamda, such as det | 1-lamda 4 | =0 | 2 3-lamda | then
