c05rc
is the AD Library version of the primal routine
c05rcf.
Based (in the C++ interface) on overload resolution,
c05rc can be used for primal, tangent and adjoint
evaluation. It supports tangents and adjoints of first order.
Note: this function can be used with AD tools other than dco/c++. For details, please contact
NAG.
c05rc
is the AD Library version of the primal routine
c05rcf.
c05rcf is a comprehensive routine that finds a solution of a system of nonlinear equations by a modification of the Powell hybrid method. You must provide the Jacobian.
For further information see
Section 3 in the documentation for
c05rcf.
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.
c05rc preserves all error codes from
c05rcf and in addition can return:
An unexpected AD error has been triggered by this routine. Please
contact
NAG.
See
Section 4.8.2 in the NAG AD Library Introduction for further information.
The routine was called using a mode that has not yet been implemented.
On entry: ad_handle is nullptr.
This check is only made if the overloaded C++ interface is used with arguments not of type double.
A C++ exception was thrown.
The error message will show the details of the C++ exception text.
Dynamic memory allocation failed for AD.
See
Section 4.8.1 in the NAG AD Library Introduction for further information.
Not applicable.
None.
The following examples are variants of the example for
c05rcf,
modified to demonstrate calling the NAG AD Library.
This example determines the values
which satisfy the tridiagonal equations:
