 *          = 'U':  Upper triangle of A is stored;  
 *          = 'L':  Lower triangle of A is stored.  
 *  
 *  N       (input) INTEGER  
 *          The order of the matrix A.  N >= 0.  
 *  
 *  A       (input/output) COMPLEX*16 array, dimension (LDA,N)  
 *          On entry, the triangular factor U or L from the Cholesky  
 *          factorization A = U**H*U or A = L*L**H, as computed by  
 *          ZPOTRF.  
 *          On exit, the upper or lower triangle of the (Hermitian)  
 *          inverse of A, overwriting the input factor U or L.  
 *  
 *  LDA     (input) INTEGER  
 *          The leading dimension of the array A.  LDA >= max(1,N).  
 *  
 *  INFO    (output) INTEGER  
 *          = 0:  successful exit  
 *          < 0:  if INFO = -i, the i-th argument had an illegal value  
 *          > 0:  if INFO = i, the (i,i) element of the factor U or L is
