LevenbergMarquardt2D Fields

The LevenbergMarquardt2D type exposes the following members.

Fields
  NameDescription
Public fieldIterations
Stored iteration values. Only used when StoreIterations is set.
Public fieldLambdaCutRel
Relative lambda value deceding when to set lambda to zero, in order to try to get quadratic convergence close to the solution.

Default value is zero (disabled). Values must be positive and reasonable values are in the range [0,1], where a value close to zero will change behavior seldomly.

Public fieldLambdaDecreaseMinFac
When decreasing lambda, this sets the minimum decrease factor

Default value is 1.0/5.0. Values must be positive and in the range [0,1].

Public fieldLambdaUpdateFactor
When updating lambda, an optimal update factor is calculated. This scales the update factor. Set greater than 1 in order to get a larger lambda, which can increase stability.

Default value is 1. Value must be positive and larger than 1.

Public fieldStoreIterations
Flag indicating whether iteration vaues should be stored in Iterations
