using mrpt::math::CLevenbergMarquardtTempl< VECTORTYPE, USERPARAM >::TFunctorEval = std::function<void( const VECTORTYPE& x, const USERPARAM& y, VECTORTYPE& out)>

The type of the function passed to execute.

The user must supply a function which evaluates the error of a given point in the solution space.

Parameters

x	The state point under examination.
y	The same object passed to "execute" as the parameter "userParam".
out	The vector of (non-squared) errors, of the average square root error, for the given "x". The functor code must set the size of this vector.

Executes the LM-method, with derivatives estimated from functor is a user-provided function which takes as input two vectors, in this order:

x: The parameters to be optimized.
userParam: The vector passed to the LM algorithm, unmodified. and must return the "error vector", or the error (not squared) in each measured dimension, so the sum of the square of that output is the overall square error.

x_increment_adder Is an optional functor which may replace the Euclidean "x_new = x + x_increment" at the core of the incremental optimizer by any other operation. It can be used for example, in on-manifold optimizations.
