ROOT::Minuit2::MinimumState Class Reference

MinimumState keeps the information (position, Gradient, 2nd deriv, etc) after one minimization step (usually in MinimumBuilder).

Constructor & Destructor Documentation

MinimumState() [1/4]

ROOT::Minuit2::MinimumState::MinimumState ( unsigned int n )

inline

Invalid state.

Definition at line 31 of file MinimumState.h.

MinimumState() [2/4]

ROOT::Minuit2::MinimumState::MinimumState ( double fval, double edm, int nfcn )

inline

Constructor without parameter values, but with function value, edm and nfcn.

This constructor will result in a state that is flagged as not valid

Definition at line 37 of file MinimumState.h.

MinimumState() [3/4]

ROOT::Minuit2::MinimumState::MinimumState ( const MinimumParameters & states, double edm, int nfcn )

inline

Constructor with only parameter values, edm and nfcn, but without errors (covariance).

The resulting state it will be considered valid, since it contains the parameter values, although it has not the error matrix (MinimumError) and HasCovariance() returns false.

Definition at line 45 of file MinimumState.h.

MinimumState() [4/4]

ROOT::Minuit2::MinimumState::MinimumState ( const MinimumParameters & states, const MinimumError & err, const FunctionGradient & grad, double edm, int nfcn )

inline

Constructor with parameters values, errors and gradient.

Definition at line 51 of file MinimumState.h.
