The specific calulation of y for a given x.

Reimplemented from CurveClass.

{
    //  e.g.   (-0.008*C10*C10 + 0.13*C10 + 0.08) * 19.8 
    return (m_parameterA * a_x * a_x + m_parameterB * a_x + m_parameterC) * m_parameterD;

Member Data Documentation

m_parameterA

double Polynomial2CurveClass::m_parameterA

protected

Parameter A.

The scaled polynomial curve takes four parameters and we also specify a X-axis range.

The form is (ParameterA*x*x + ParameterB*x + ParameterC) * ParameterD
