Hello,
I am trying to get the eigenvalues and eigenvectors of an
Hermitian matrix. An hermitian matrix has the property of being
its own transpose-conjugate:
A = CONJ(TRANSPOSE(A)) => A[i,j] = CONJ(A[j,i])
In fact, the real-symmetric matrices are just a special case of hermitian
and finding eigenvalues and vectors should be as easy as for real-symm.,
but all the routines in the IDL standard library ask you for real ones
(symmetric or not, depending on provedure).
Has anybody implemented an equivalent of EIGENQL (or even
ELMHES/HQR/EIGENVEC set)? If not, does anybody know the procedure to
reduce a Hermitian matrix to tridiagonal form (with complex arithmetics)?
Many thanks,
