Class Scine::Utils::UpdateFunctionManagerBase

class UpdateFunctionManagerBase

This class manages the two different update functions that are neccessary for a least squares optimization using Eigen.

Public Functions

virtual void updateErrors(const Eigen::VectorXd &parameters, Eigen::VectorXd &errors) = 0

Update the errors vector for the least squares optimization for a given set of parameters.

Parameters

  • parameters: The parameters.

  • errors: The error vector to update within this function.

void updateJacobian(const Eigen::VectorXd &parameters, Eigen::MatrixXd &jacobian)

Update the Jacobian matrix for the least squares optimization for a given set of parameters. 

   The base implementation is a numerical Jacobian.
Parameters

  • parameters: The parameters.

  • jacobian: The Jacobian matrix to update within this function.

virtual int getNumberOfDataPoints(const Eigen::VectorXd &parameters) const = 0

This function returns the number of data points present in the least squares optimization.

Return

The number of data points present in the least squares optimization.

Parameters

  • parameters: The parameters.
