(Constructor)

Class for Cauchy Point trust region minimisation specific functions.

Unless you know what you are doing, you should call the function 'cauchy_point' rather than using this class.

Overrides: base_classes.Min.__init__

update(self)

Update function.

Function to update the function value, gradient vector, and Hessian matrix.

Overrides: base_classes.Min.update
