-*  Purpose
-*  =======
-*
-*  DGETRI computes the inverse of a matrix using the LU factorization
-*  computed by DGETRF.
-*
-*  This method inverts U and then computes inv(A) by solving the system
-*  inv(A)*L = inv(U) for inv(A).
-*
-*  Arguments
-*  =========
-*
-*  N       (input) INTEGER
-*          The order of the matrix A.  N >= 0.
-*
-*  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
-*          On entry, the factors L and U from the factorization
-*          A = P*L*U as computed by DGETRF.
-*          On exit, if INFO = 0, the inverse of the original matrix A.

-*  LDA     (input) INTEGER
-*          The leading dimension of the array A.  LDA >= max(1,N).
-*
-*  IPIV    (input) INTEGER array, dimension (N)
-*          The pivot indices from DGETRF; for 1<=i<=N, row i of the
-*          matrix was interchanged with row IPIV(i).
-*
-*  WORK    (workspace/output) DOUBLE PRECISION array, dimension (MAX(1,LWORK))
-*          On exit, if INFO=0, then WORK(1) returns the optimal LWORK.
-*
-*  LWORK   (input) INTEGER
-*          The dimension of the array WORK.  LWORK >= max(1,N).
-*          For optimal performance LWORK >= N*NB, where NB is
-*          the optimal blocksize returned by ILAENV.
-*
-*          If LWORK = -1, then a workspace query is assumed; the routine
-*          only calculates the optimal size of the WORK array, returns
-*          this value as the first entry of the WORK array, and no error
