  PLASMA_zgelqs - Compute a minimum-norm solution min || A*X - B || using the LQ factorization A = L*Q computed by PLASMA_zgelqf. Parameters
  [in] | M | The number of rows of the matrix A. M >= 0.
  [in] | N | The number of columns of the matrix A. N >= M >= 0.
  [in] | NRHS | The number of columns of B. NRHS >= 0.
  [in] | A | Details of the LQ factorization of the original matrix A as returned by PLASMA_zgelqf.
  [in] | LDA | The leading dimension of the array A. LDA >= M.
  [in] | descT | Auxiliary factorization data, computed by PLASMA_zgelqf.
  [in,out] | B | On entry, the M-by-NRHS right hand side matrix B. On exit, the N-by-NRHS solution matrix X.
  [in] | LDB | The leading dimension of the array B. LDB >= N.
  Returns Return values
  PLASMA_SUCCESS | successful exit
  <0 | if -i, the i-th argument had an illegal value
