  PLASMA_sgels_Tile - Solves overdetermined or underdetermined linear system of equations using the tile QR or the tile LQ factorization. Tile equivalent of PLASMA_sgels(). Operates on matrices stored by tiles. All matrices are passed through descriptors. All dimensions are taken from the descriptors. Parameters
  [in] | trans | Intended usage: = PlasmaNoTrans: the linear system involves A; = PlasmaTrans: the linear system involves A**T. Currently only PlasmaNoTrans is supported.
  [in,out] | A | On entry, the M-by-N matrix A. On exit, if M >= N, A is overwritten by details of its QR factorization as returned by PLASMA_sgeqrf; if M < N, A is overwritten by details of its LQ factorization as returned by PLASMA_sgelqf.
  [out] | T | On exit, auxiliary factorization data.
  [in,out] | B | On entry, the M-by-NRHS matrix B of right hand side vectors, stored columnwise; On exit, if return value = 0, B is overwritten by the solution vectors, stored columnwise: if M >= N, rows 1 to N of B contain the least squares solution vectors; the residual sum of squares for the solution in each column is given by the sum of squares of the modulus of elements N+1 to M in that column; if M < N, rows 1 to N of B contain the minimum norm solution vectors;
Returns PLASMA_SUCCESS successful exit See Also PLASMA_sgels PLASMA_sgels_Tile_Async PLASMA_cgels_Tile PLASMA_dgels_Tile PLASMA_sgels_Tile
