Vector

Simple N-dimensional Vector math library. Uses standard []float64 type.

Quick Example

package main

import (
  "fmt"
  "github.com/atedja/go-vector"
)

func main() {
  v1 := vector.New(4)
  v2 := vector.NewWithValues([]float64{0.0, 1.0, 2.0, 3.0})

  result := vector.Add(v1, v2)
}

Basic Usage

Creating Vectors

var v vector.Vector
v = vector.New(3)
v = vector.NewWithValues([]float64{0.0, 1.0, 2.0})

Scale Vectors

v.Scale(2.0)

Dot and Cross Products

v1 := vector.NewWithValues([]float64{0.0, 1.0, 2.0})
v2 := vector.NewWithValues([]float64{2.0, -1.0, 4.0})
cross, _ := vector.Cross(v1, v2)
dot, _ := vector.Dot(v1, v2)

In general, all functions under vector package are designed to always return a new result without modifying the vectors in the arguments, while functions under the vector.Vector type will modify the vector.
