Hi I am using the Lapack routine DSYGV and I have some questions about its
results.
I use DSYGV in a C program in which I want to compute the eigenvalues and the
eigenvectors of two real symmetric matrices AT and BT:the function is
dsygv_(& ITYPE, &JOBZ, &UPLO, &N, AT, &LDA, BT, &LDB, eval, WORK,
&LWORK,&INFO );
The parameters I set are
ITYPE=1; /*the problem is AT*x=lambda*BT*x */
JOBZ= 'V'; /*I want eigenvalues AND eigenvectors*/
UPLO= 'U';
N= 2;
LDA= 2;
LDB= 2;
LWORK= 8;
How can I read the matrix Z of eigenvectors, that is contained in the matrix
AT, and visualize it in the output of the program?
The matrix AT is overwritten by Z?
Thanks for your support,
Alessandra Bonardi.
