?syevd function

Computes all eigenvalues and, optionally, all eigenvectors of a real symmetric matrix using divide and conquer algorithm.

Fortran-77 Interface

Calling from Fortran:
call ssyevd(job, uplo, n, a, lda, w, work, lwork, iwork, liwork, info) call dsyevd(job, uplo, n, a, lda, w, work, lwork, iwork, liwork, info)
Calling from C:
ssyevd(job, uplo, n, a, lda, w, work, lwork, iwork, liwork, info); dsyevd(job, uplo, n, a, lda, w, work, lwork, iwork, liwork, info);

C Interface

lapack_int LAPACKE_ssyevd(int matrix_layout, char jobz, char uplo, lapack_int n, float* a, lapack_int lda, float* w); lapack_int LAPACKE_dsyevd(int matrix_layout, char jobz, char uplo, lapack_int n, double* a, lapack_int lda, double* w);
