!> DLAUU2 computes the product U * U**T or L**T * L, where the triangular
!> factor U or L is stored in the upper or lower triangular part of
!> the array A.
!>
!> If UPLO = 'U' or 'u' then the upper triangle of the result is stored,
!> overwriting the factor U in A.
!> If UPLO = 'L' or 'l' then the lower triangle of the result is stored,
!> overwriting the factor L in A.
!>
!> This is the unblocked form of the algorithm, calling Level 2 BLAS.

UPLO

!>          UPLO is CHARACTER*1
!>          Specifies whether the triangular factor stored in the array A
!>          is upper or lower triangular:
!>          = 'U':  Upper triangular
!>          = 'L':  Lower triangular
!> 

N

!>          N is INTEGER
!>          The order of the triangular factor U or L.  N >= 0.
!> 

A

!>          A is 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.
!> 

LDA

!>          LDA is INTEGER
!>          The leading dimension of the array A.  LDA >= max(1,N).
!> 

INFO

!>          INFO is INTEGER
!>          = 0: successful exit
!>          < 0: if INFO = -k, the k-th argument had an illegal value
