  PLASMA_dorglq - Generates an M-by-N matrix Q with orthonormal rows, which is defined as the first M rows of a product of the elementary reflectors returned by PLASMA_dgelqf. Parameters
  [in] | M | The number of rows of the matrix Q. M >= 0.
  [in] | N | The number of columns of the matrix Q. N >= M.
  [in] | K | The number of rows of elementary tile reflectors whose product defines the matrix Q. M >= K >= 0.
  [in] | A | Details of the LQ factorization of the original matrix A as returned by PLASMA_dgelqf.
  [in] | LDA | The leading dimension of the array A. LDA >= max(1,M).
  [in] | descT | Auxiliary factorization data, computed by PLASMA_dgelqf.
  [out] | Q | On exit, the M-by-N matrix Q.
  [in] | LDQ | The leading dimension of the array Q. LDQ >= max(1,M).
  Returns Return values
  PLASMA_SUCCESS | successful exit
  PLASMA_SUCCESS | <0 if -i, the i-th argument had an illegal value
