Types ¶

type Dump ¶

type Dump struct {
	Order  int       `json:"order"`
	Points []TFPoint `json:"points"`
}

Dump is a serializable representation of a TabulatedFunction.

type TFPoint ¶

type TFPoint struct {
	X, Y *big.Float
	// contains filtered or unexported fields
}

type TabulatedFunction ¶

type TabulatedFunction struct {

	//
	P []TFPoint
	// contains filtered or unexported fields
}

func New ¶

func New() *TabulatedFunction

Create

func (*TabulatedFunction) AddPoint ¶

func (f *TabulatedFunction) AddPoint(Xn, Yn *big.Float, epoch uint32) *big.Float

func (*TabulatedFunction) Assign ¶

func (*TabulatedFunction) DrawPS ¶

func (f *TabulatedFunction) DrawPS(path string) error

func (*TabulatedFunction) Dump ¶

func (f *TabulatedFunction) Dump() *Dump

Dump generates a serializable dump for a tabulated function.

func (*TabulatedFunction) Epoch ¶
