Functions

func ApproximateDerivative

func ApproximateDerivative(f common.System, x_0 mat.Vector) mat.Matrix

func FindRoot

func FindRoot(f common.System, D common.Derivative,
	x_0 mat.Vector, params *Params) (mat.Vector, error)

FindRoot uses the simplified Newton method in order to approximate a root. The derivate is required to be invertable at x_0, otherwise error is thrown. D is optional and if not given it will be approximated.
