[in] | jobz | Intended usage: = PlasmaNoVec: computes eigenvalues only; = PlasmaVec: computes eigenvalues and eigenvectors. |
[in] | uplo | Specifies whether the matrix A is upper triangular or lower triangular: = PlasmaUpper: Upper triangle of A is stored; = PlasmaLower: Lower triangle of A is stored. |
[in] | N | The order of the matrix A. N >= 0. |
[in,out] | A | On entry, the symmetric (or Hermitian) matrix A. If uplo = PlasmaUpper, the leading N-by-N upper triangular part of A contains the upper triangular part of the matrix A, and the strictly lower triangular part of A is not referenced. If uplo = PlasmaLower, the leading N-by-N lower triangular part of A contains the lower triangular part of the matrix A, and the strictly upper triangular part of A is not referenced. On exit, the lower triangle (if uplo = PlasmaLower) or the upper triangle (if uplo = PlasmaUpper) of A, including the diagonal, is destroyed. |
[in] | LDA | The leading dimension of the array A. LDA >= max(1,N). |
[out] | W | On exit, if info = 0, the eigenvalues. |
[in,out] | descT | On entry, descriptor as return by PLASMA_Alloc_Workspace_zheev On exit, contains auxiliary factorization data. |
[out] | Q | On exit, if jobz = PlasmaVec and info = 0, the eigenvectors. |
[in] | LDQ | The leading dimension of the array Q. LDQ >= max(1,N). |
