How to get the global eigenvectors from PDSYEVD
Posted: Wed Dec 07, 2011 3:28 pmHello,
I was wondering how to transform the local output of eigenvectors Z generated by PDSYEVD:
PDSYEVD( 'V', 'U', N, A, 1, 1, DESCA, EIGENVAL, Z, 1, 1, DESCZ, WORK, LWORK,IWORK, LIWORK, INFO )
into global representation. Ie how to Z(local) -----> Z(global) ?
