## Classes
class | IG.Num.ScalarFunctionConstant
| Constant scalar function of vector variable. Function is evaluated according to f(x) = c where x is vector of parameters, and c is the constant scalar term (function value at x=0). More...
class | IG.Num.ScalarFunctionLinear
| Linear scalar function of vector variable. Function is evaluated according to q(x) = b^T*x + c where x is vector of parameters, b is vector of linear coefficients (gradient at x=0) and c is the scalar term (function value at x=0). More...
class | IG.Num.ScalarFunctionQuadratic
| Quadratic scalar function of vector variable. Function is evaluated according to q(x) = (1/2)*x^T*G*x + b^T*x + c where x is vector of parameters, G is constant Hessian matrix, b is vector of linear coefficients (gradient at x=0) and c is the scalar term (function value at x=0). More...
class | IG.Num.ScalarFunctionExamples
| Various examples of scalar functions. More...
class | IG.Num.ScalarFunctionExamples.Rosenbrock
| RosenBrock function. f(x,y) = (1-x)^2 + 100 * (y-x^2)^2 More...
class | IG.Num.ScalarFunctionExamples.RosenbrockGeneralizedAdjacent
| Generalzed multivariate RosenBrock function for Dim >= 2. More...
class | IG.Num.ScalarFunctionExamples.RosenbrockGeneralizedExhaustive
| Generalzed multivariate RosenBrock function for Dim >= 2. More...
class | IG.Num.ScalarFunctionExamples.ParaboloidSymmetric2D
| Symmetric paraboloid centered at coordinate origin. f(x,y) = x^2 + y^2 - R2. If R2 is positive then 0-level is a circle, if it is negative then the paraboloid does not intersect with zero-plane. Default is R2 = 1 (default constructor). More...
class | IG.Num.ScalarFunctionExamples.Quadratic2d
| Example quadratic polynomial in 2D. f(x,y) = 2*x^2 + y^2 + x*y + x + y + 10. More...
class | IG.Num.ScalarFunctionExamples.Quadratic3d
| Example quadratic polynomial in 3D. f(x,y,z) = x*x + 2*y*y + 4*z*z + x*y + 2*y*z + 4*z*x + x + y + z + 10 More...
