Detailed Description

template<typename TInternalComputationValueType>
class itk::SingleValuedCostFunctionv4Template< TInternalComputationValueType >

This class is a base for a CostFunction that returns a single value.

This class differs from the SingleValuedCostFunction in that it is fine tunned for managing very large numbers of parameters. For example, to be used in conditions where the number of parameters is in the range of thousands or even millions. Due to the large number of parameters, the API of this class avoids any copying of the parameters array, and of the classes that have dimensionality related to the size of the parameters array.

As you look at the code of this class, keep in mind that the types ParametersType and DerivativeType will be some sort of array-like type with millions of elements.

Derived classes must provide implementations for: GetValue GetValueAndDerivative
