Detailed Description

template<typename Lambda>
class MathUtils::VectorLambda< Lambda >

Lambda wrapper for N-D objective functions (value only). Wraps a lambda/callable into a functor with Value() method.

Usage:

auto aFunc = VectorLambda([](const math_Vector& x, double& y) {
  y = x(1)*x(1) + x(2)*x(2);  // Sphere function
  return true;
});
auto aResult = MathOpt::Powell(aFunc, aStartPoint);

Template Parameters

Lambda callable type with signature bool(const math_Vector&, double&)
