valvector_ad_join¶
View page sourceJoin a Vector of AD valvectors¶
Join a vector of AD<valvector>, each with size one, into one AD<valvector>.
Syntax¶
m¶
We use m to denote ax_vec .size() .
ax_vec¶
This is a SimpleVector with elements of type CppAD::AD<valvector> .
It is const and is passed by reference.
For i = 0 , … , m - 1 ,
the size ax [ i ].size() is one.
ay¶
This CppAD::AD<valvector> is passed by reference and its input value does not matter. Upon return, its size in m and for i = 0 , … , m - 1
ay[i] = ax_vec[i][0]
Example¶
The file valvector_ad_join.cpp is an example and test of this operation.
