	// contains filtered or unexported fields
}

func New

func New(gt GeneratorType, seed uint64) *Generator

func NewTimeSeed

func NewTimeSeed(gt GeneratorType) *Generator

func (*Generator) Uniform

func (gen *Generator) Uniform(low, high float64) float64

func (*Generator) UniformAt

func (gen *Generator) UniformAt(low, high float64, target []float64)

func (*Generator) UniformInt

func (gen *Generator) UniformInt(low, high int) int

type GeneratorType

type GeneratorType uint8

const (
	Xorshift GeneratorType = iota
	Golang
	Tausworthe

	Default = Tausworthe
)

type SobolSequence

type SobolSequence struct {
	// contains filtered or unexported fields
}

func NewSobolSequence

func NewSobolSequence() *SobolSequence

See Press et al. 2007.

func (*SobolSequence) Init

func (seq *SobolSequence) Init()

See Press et al. 2007.

func (*SobolSequence) Next

func (seq *SobolSequence) Next(dim int) []float64

See Press et al. 2007.

func (*SobolSequence) NextAt

func (seq *SobolSequence) NextAt(target []float64)

NextAt is equivelent to Next, except the Sobol sequence is returned in-place.
