Functions

func Concat

func Concat(xss ...[]float64) []float64

Concat returns the concatenation of its arguments. It does not modify its inputs.

func Linspace

func Linspace(lo, hi float64, num int) []float64

Linspace returns num values spaced evenly between lo and hi, inclusive. If num is 1, this returns an array consisting of lo.

func Logspace

func Logspace(lo, hi float64, num int, base float64) []float64

Logspace returns num values spaced evenly on a logarithmic scale between base**lo and base**hi, inclusive.

func Map

func Map(f func(float64) float64, xs []float64) []float64

Map returns f(x) for each x in xs.

f may be evaluated in parallel and in any order.

func Sum

func Sum(xs []float64) float64

Sum returns the sum of xs.

func Vectorize

func Vectorize(f func(float64) float64) func(xs []float64) []float64

Vectorize returns a function g(xs) that applies f to each x in xs.

f may be evaluated in parallel and in any order.
