  PLASMA_cheev_Tile - Computes all eigenvalues and, optionally, eigenvectors of a complex Hermitian matrix A using a two-stage approach: First stage: reduction to band tridiagonal form; Second stage: reduction from band to tridiagonal form. Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors. Parameters
  [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,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 = 'L', 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, if jobz = PlasmaVec, then if return value = 0, A contains the orthonormal eigenvectors of the matrix A. If jobz = PlasmaNoVec, then on exit the lower triangle (if uplo = PlasmaLower) or the upper triangle (if uplo = PlasmaUpper) of A, including the diagonal, is destroyed.*
  [out] | W | On exit, if info = 0, the eigenvalues.
  [in,out] | T | On entry, descriptor as return by PLASMA_Alloc_Workspace_cheev On exit, contains auxiliary factorization data.
  [out] | Q | On exit, if jobz = PlasmaVec and info = 0, the eigenvectors.
  [in] | LDQ | The leading dimention of the eigenvectors matrix Q. LDQ >= max(1,N).
  Returns Return values
  PLASMA_SUCCESS | successful exit
  <0 | if -i, the i-th argument had an illegal value
  >0 | if INFO = i, the algorithm failed to converge; i off-diagonal elements of an intermediate tridiagonal form did not converge to zero.
