!>
!> DLARGE pre- and post-multiplies a real general n by n matrix A
!> with a random orthogonal matrix: A = U*D*U'.
!> 

N

!>          N is INTEGER
!>          The order of the matrix A.  N >= 0.
!> 

A

!>          A is DOUBLE PRECISION array, dimension (LDA,N)
!>          On entry, the original n by n matrix A.
!>          On exit, A is overwritten by U*A*U' for some random
!>          orthogonal matrix U.
!> 

LDA

!>          LDA is INTEGER
!>          The leading dimension of the array A.  LDA >= N.
!> 

ISEED

!>          ISEED is INTEGER array, dimension (4)
!>          On entry, the seed of the random number generator; the array
!>          elements must be between 0 and 4095, and ISEED(4) must be
!>          odd.
!>          On exit, the seed is updated.
!> 

WORK

!>          WORK is DOUBLE PRECISION array, dimension (2*N)
!> 

INFO

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