| org.hipparchus.optim.nonlinear.vector.leastsquares | This package provides algorithms that minimize the residuals
 between observations and model values. | 
| Modifier and Type | Method and Description | 
|---|---|
| GaussNewtonOptimizer | GaussNewtonOptimizer. withDecomposer(MatrixDecomposer newDecomposer)Configure the matrix decomposition algorithm. | 
| GaussNewtonOptimizer | GaussNewtonOptimizer. withDecomposition(GaussNewtonOptimizer.Decomposition newDecomposition)Deprecated. 
 Use  withDecomposer(MatrixDecomposer)andwithFormNormalEquations(boolean)instead. the new methods allow the numerical
 tolerance of the decomposition to be set. | 
| GaussNewtonOptimizer | GaussNewtonOptimizer. withFormNormalEquations(boolean newFormNormalEquations)Configure if the normal equations should be explicitly formed. |
