 *  
 *  DLAUU2 computes the product U * U**T or L**T * L, where the triangular

 *  
 *  Arguments  
 *  =========  
 *  
 *  UPLO    (input) CHARACTER*1  
 *          Specifies whether the triangular factor stored in the array A  
 *          is upper or lower triangular:  
 *          = 'U':  Upper triangular  
 *          = 'L':  Lower triangular  
 *  
 *  N       (input) INTEGER  
 *          The order of the triangular factor U or L.  N >= 0.  
 *  
 *  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)  
 *          On entry, the triangular factor U or L.  
 *          On exit, if UPLO = 'U', the upper triangle of A is  
 *          overwritten with the upper triangle of the product U * U**T;  
 *          if UPLO = 'L', the lower triangle of A is overwritten with  
 *          the lower triangle of the product L**T * L.
