6C  Subroutine CDCOR is called to compute corrections to the Y array.
7C  In the case of functional iteration, update Y directly from the
8C  result of the last call to F.
9C  In the case of the chord method, compute the corrector error and
10C  solve the linear system with that as right hand side and DFDY as
11C  coefficient matrix, using the LU decomposition if MITER is 1, 2, 4,
12C  or 5.
