Hi,

I want to get the angle corresponding to a given quaternion Q. Now with 
Eigen "Q.toAxisAngle(..,..)" is no more available, and I tried (after 
giving a look to /usr/include/eigen2/Eigen/src/Geometry/AngleAxis.h, and 
https://yade-dem.org/wiki/Wm3%E2%86%92Eigen) :

Real angle;
AxisAngle aa(Q);
angle = aa.angle();

But I get this compilation error : error: 'AxisAngle' was not declared 
in this scope

So, which file - if this is the reason - do I have to include ? (with 
#include "/usr/include/eigen2/Eigen/src/Geometry/AngleAxis.h", it does 
not work)

Thanks a lot,

Jerome
