Type.createClass(
	'Gemstone.Numeric.Interpolation.PiecewiseLinearFunction');

Inheritance: Object PiecewiseLinearFunction

Remarks

The conversion function returned by this class uses a binary search algorithm to find the appropriate line segment to use for the calculation. Therefore, the domain must be specified either in increasing or decreasing order.

Here is an example of how to use this class.


            Func<double, double> piecewiseLinearFunc = new PiecewiseLinearFunction()
                .SetDomain(-1, 0, 1)
                .SetRange(0, 1, 0);
                
            Console.WriteLine(piecewiseLinearFunc(-10));   // -9
            Console.WriteLine(piecewiseLinearFunc(-1));    // 0 
            Console.WriteLine(piecewiseLinearFunc(-0.5));  // 0.5
            Console.WriteLine(piecewiseLinearFunc(0));     // 1
            Console.WriteLine(piecewiseLinearFunc(0.5));   // 0.5
            Console.WriteLine(piecewiseLinearFunc(1));     // 0
            Console.WriteLine(piecewiseLinearFunc(10));    // -9

Constructors

PiecewiseLinearFunction

Initializes a new instance of the PiecewiseLinearFunction class

Properties

Domain	Gets the x-values of the pivot points in the piecewise linear function.
Range	Gets the y-values of the pivot points in the piecewise linear function.

Methods

Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
SetDomain	Sets the x-values of the pivot points in the piecewise linear function.
SetRange	Sets the y-values of the pivot points in the piecewise linear function.
ToString	Returns a string that represents the current object. (Inherited from Object)

Operators

(PiecewiseLinearFunction to FuncDouble, Double)

Converts the PiecewiseLinearFunction object to a FuncT, TResult to start converting values.
