is the AD Library version of the primal routine
Based (in the C++ interface) on overload resolution,
f07ce can be used for primal, tangent and adjoint
evaluation. It supports tangents and adjoints of first order.
Corresponding to the overloaded C++ function, the Fortran interface provides five routines with names reflecting the type used for active real arguments. The actual subroutine and type names are formed by replacing AD and ADTYPE in the above as follows:
f07cef (dgttrs) computes the solution to a real system of linear equations or , where is an tridiagonal matrix and and are matrices, using the factorization returned by f07cdf.
For further information see Section 3 in the documentation for f07cef (dgttrs).

In addition to the arguments present in the interface of the primal routine,
f07ce includes some arguments specific to AD.
A brief summary of the AD specific arguments is given below. For the remainder, links are provided to the corresponding argument from the primal routine.
A tooltip popup for all arguments can be found by hovering over the argument name in Section 2 and in this section.
