 objects.
These objects are used to <a href="glossary.xml#Tape" target="_top"><span style='white-space: nowrap'>tape</span></a>

an AD of

This operation sequence can
be transferred to an <a href="adfun.xml" target="_top"><span style='white-space: nowrap'>ADFun</span></a>
 object where it
can be used to evaluate the corresponding 
function and derivative values.
