g01fb
is the AD Library version of the primal routine
g01fbf.
Based (in the C++ interface) on overload resolution,
g01fb 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.
g01fb
is the AD Library version of the primal routine
g01fbf.
g01fbf returns the deviate associated with the given tail probability of Student's
-distribution with real degrees of freedom.
For further information see
Section 3 in the documentation for
g01fbf.
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.
Note that the primal routine
is a function whereas
g01fb_a1w_f,
is a subroutine, where the function value is returned in the additional output parameter,
x.
g01fb preserves all error codes from
g01fbf and in addition can return:
An unexpected AD error has been triggered by this routine. Please
contact
NAG.

Error Handling in the NAG AD Library Introduction for further information.
The routine was called using a strategy that has not yet been implemented.
See
AD Strategies in the NAG AD Library Introduction for further information.
A C++ exception was thrown.
The error message will show the details of the C++ exception text.
Dynamic memory allocation failed for AD.

Not applicable.
None.
The following examples are variants of the example for
g01fbf,
modified to demonstrate calling the NAG AD Library.
This example reads the probability, the tail that probability represents and the degrees of freedom for a number of Student's -distributions and computes the corresponding deviates.
