  PLASMA_sgesvd_Tile - computes the singular value decomposition (SVD) of a complex M-by-N matrix A, optionally computing the left and/or right singular vectors. Tile equivalent of PLASMA_sgesvd(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors. Parameters
  [in] | jobu | Specifies options for computing all or part of the matrix U. Intended usage: = PlasmaVec: all M columns of U are returned in array U; = PlasmaNoVec: no columns of U (no left singular vectors) are computed.
  [in] | jobvt | Specifies options for computing all or part of the matrix V**T. Intended usage: = PlasmaVec: all M columns of U are returned in array U; = PlasmaNoVec: no columns of U (no left singular vectors) are computed.
  [in,out] | A | On entry, the M-by-N matrix A. On exit, if JOBU = 'O', A is overwritten with the first min(m,n) columns of U (the left singular vectors, stored columnwise); if JOBVT = 'O', A is overwritten with the first min(m,n) rows of V**T (the right singular vectors, stored rowwise); if JOBU .ne. 'O' and JOBVT .ne. 'O', the contents of A are destroyed.
  [out] | S | The singular values of A, sorted so that S(i) >= S(i+1).
  [out] | U | (LDU,M) if JOBU = 'A' or (LDU,min(M,N)) if JOBU = 'S'. If JOBU = 'A', U contains the M-by-M unitary matrix U; if JOBU = 'S', U contains the first min(m,n) columns of U (the left singular vectors, stored columnwise); if JOBU = 'N' or 'O', U is not referenced.
  [out] | VT | If JOBVT = 'A', VT contains the N-by-N unitary matrix V**T; if JOBVT = 'S', VT contains the first min(m,n) rows of V**T (the right singular vectors, stored rowwise); if JOBVT = 'N' or 'O', VT is not referenced.
  [out] | T | On exit, auxiliary factorization data.
Returns PLASMA_SUCCESS successful exit See Also PLASMA_sgesvd PLASMA_sgesvd_Tile_Async PLASMA_cgesvd_Tile PLASMA_dgesvd_Tile PLASMA_sgesvd_Tile
