gtsam::NoiseModelFactor1< VALUE > Class Template Referenceabstract
Detailed Description
template<class VALUE>
class gtsam::NoiseModelFactor1< VALUE >
A convenient base class for creating your own NoiseModelFactor with 1 variable.
To derive from this class, implement evaluateError().
Templated on a values structure type. The values structures are typically more general than just vectors, e.g., Rot3 or Pose3, which are objects in non-linear manifolds (Lie groups).
