Hi,<br>
<br>
I used a std::vector<double> as intermediate type for
Eigen::VectorXd.<br>

This is a very bad idea. You should use <br>

Yes, by today it seems a bad idea. But back when doing it, it was
the most obvious idea. <br>

Now in base/actuators/command it takes Eigen::VectorX instead of
std::vector<double> for the ruby type (<a

Is that done automatically?</blockquote>
Yes.<br>

Yes, by NOT telling the type system that std::vector<double>
is equivalent to Eigen::VectorXd. Create a specific type
wrappers::VectorXd.<br>
</blockquote>
Would a typedef already help, or more like a vector in a struct?
