# 余弦相似度
# 一、安装
```bash
go get -u github.com/golang-infrastructure/go-cosine-similarity
```
# 二、示例代码
```go
package main
import (
"fmt"
cosine_similarity "github.com/golang-infrastructure/go-cosine-similarity"
)
func main() {
sliceA := []int{1, 1, 2, 1, 1, 1, 0, 0, 0}
sliceB := []int{1, 1, 1, 0, 1, 1, 1, 1, 1}
r, err := cosine_similarity.NumberSliceCosineSimilarityE(sliceA, sliceB)
if err != nil {
fmt.Println(err.Error())
return
}
fmt.Println(r)
// Output:
// 0.7071067811865475
}
