Namespaces
namespace	MathUtils
	Modern math solver types and result structures.

Functions
bool	MathUtils::IsXConverged (double theXOld, double theXNew, double theTolerance)
	Check convergence based on relative change in X. Uses relative tolerance scaled by current value magnitude.
bool	MathUtils::IsFConverged (double theFValue, double theTolerance)
	Check convergence based on absolute function value.
bool	MathUtils::IsConverged (double theXOld, double theXNew, double theFValue, const Config &theConfig)
	Combined convergence test for scalar root finders. Checks both X convergence and function value convergence.
bool	MathUtils::IsMinConverged (double theXOld, double theXNew, double theFOld, double theFNew, const Config &theConfig)
	Convergence test for minimization (checks both X and F change).
bool	MathUtils::IsVectorConverged (const math_Vector &theOld, const math_Vector &theNew, double theTolerance)
	Convergence test for vector solvers using infinity norm.
bool	MathUtils::IsGradientConverged (const math_Vector &theGradient, double theTolerance)
	Convergence test using gradient norm for minimization.
double	MathUtils::InfinityNorm (const math_Vector &theVector)
	Compute infinity norm of a vector.
double	MathUtils::EuclideanNorm (const math_Vector &theVector)
	Compute Euclidean (L2) norm of a vector.
