Eigenvalues/eigenvectors of hermitian matrices

Postby Boris_MV » Fri Dec 19, 2014 9:55 pm

Hi there,

Please help. I was testing calculation of eigenvectors/eigenvalues with ZHEEV on a 3x3 hermitian matrx and got this strange error: all three eigenvectors are OK, but one eigenvalue is WRONG!
What is going on here?
Short Fortran code and the result are in the attached txt file. Thanks.
Short Fortran code calling ZHEEV. Result included.
