f06ya
is the AD Library version of the primal routine
f06yaf (dgemm).
Based (in the C++ interface) on overload resolution,
f06ya 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.
f06ya
is the AD Library version of the primal routine
f06yaf (dgemm).
f06yaf (dgemm) performs one of the matrix-matrix operations
where
,

is always
.
For further information see
Section 3 in the documentation for
f06yaf (dgemm).
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.
There are no specific error codes from
f06yaf (dgemm), however
f06ya can return:
An unexpected AD error has been triggered by this routine. Please
contact
NAG.
See
Error Handling in the NAG AD Library Introduction for further information.
The routine was called using a strategy that has not yet been implemented.

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.
