Detailed Description

Secant predictor computation class

This class computes the predictor direction given by the secant vector to the continuation curve. The secant vector calculation is implemented by the computeSecant method of the LOCA::Continuation::Group class.

The parameters used by this class supplied in the constructor or reset method are:

• "First Step Predictor" Predictor sublist for first step
