# Vector

[![Build Status](https://travis-ci.org/atedja/go-vector.svg?branch=master)](https://travis-ci.org/atedja/go-vector)

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

### Quick Example

```go

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)

}

```

#### [Full API Documentation](https://godoc.org/github.com/atedja/go-vector)

### 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.
