LevenbergMarquardt2D Properties

Properties

Epsilon Epsilon, used in stopping criteria

Default value is 1e-9

LambdaScaling Scaling factor in J^T*J+lambda*I, replacing the diagonal of I by those in LambdaScaling

By default they are [1,1]. They can not be negative.

MaxIter Maximum number of iterations. Default 100
MaxLineSearchIter Maximum number of line search iterations. Default 0.
NumFunctionEval Hold the number of function evaluations.
NumIter Hold the actual number of iterations for the last solve.
NumJacobianEval Hold the number of Jacobian evaluations.
UseLineSearch Flag specifying whether a line search approach is to be used. Default false.
UseLm Flag whether a LM algorithm should be used. Default true. If set to false the Newton-Raphson method will be used. The Newton-Raphson method can only be used for finding zeros, not for minimizing.
