            Methods
| Clone | 
            Constructs an exact copy of this instance.
             (Inherited from Curve)  | 
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object)  | 
| Fill | 
            Fills a dense vector with the partial derivatives of the curve with respect to
            each of the curve parameters computed using numerical differentiation.
             (Inherited from NonlinearCurve)  | 
| Fill | 
            Fills a dense vector with the partial derivatives of the curve with respect to
            each of the curve parameters.
             (Overrides NonlinearCurve.FillPartialDerivatives(Double, DenseVector<Double>))  | 
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)  | 
| Find | 
            Gets the set of X-coordinates where the curve crosses
            the X-axis.
             (Inherited from Curve)  | 
| Get | 
            Returns a CurveFitter object that can be used to fit the curve to data.
             (Inherited from NonlinearCurve)  | 
| Get | 
            Returns a Curve that represents the derivative
            of this Curve.
             (Inherited from Curve)  | 
| Get | Serves as the default hash function. (Inherited from Object)  | 
| Get | 
            Returns a vector containing initial values for the parameters for a curve fit
            through on the specified data.
             (Overrides NonlinearCurve.GetInitialFitParameters(Vector<Double>, Vector<Double>))  | 
| Get | 
            Returns a vector with the partial derivatives 
            of the curve with respect to each of the curve parameters.
             (Inherited from NonlinearCurve)  | 
| Get | Gets the Type of the current instance. (Inherited from Object)  | 
| Integral | 
            Gets the definite integral of the curve between the
            specified X-coordinates.
             (Inherited from Curve)  | 
| Memberwise | Creates a shallow copy of the current Object. (Inherited from Object)  | 
| OnParameter | 
            Called after a Curve parameter has been changed.
             (Inherited from Curve)  | 
| OnParameter | 
            Called before the value of a curve parameter is changed.
             (Inherited from Curve)  | 
| Set | 
            Sets the curve parameters to initial values based on the specified data.
             (Inherited from NonlinearCurve) Obsolete.  | 
| Set | 
            Sets a curve parameter to the specified value.
             (Inherited from Curve)  | 
| Slope | 
            Gets the slope of the curve at the specified
            X-coordinate.
             (Overrides Curve.SlopeAt(Double))  | 
| Solve | 
            Finds the x value where the curve reaches the specified y value.
             (Inherited from Curve)  | 
| Tangent | 
            Gets the tangent line to the curve at the
            specified X-coordinate.
             (Inherited from Curve)  | 
| ToString | Returns a string that represents the current object. (Inherited from Object)  | 
| Value | 
            Gets the Y-value of the curve at the specified
            X-coordinate.
             (Overrides Curve.ValueAt(Double))  |
