# vScopy(_:_:_:)

Copies one vector to another.

## Declaration

```swift
func vScopy(_ n: Int32, _ x: UnsafePointer<vFloat>, _ y: UnsafeMutablePointer<vFloat>)
```

## Parameters

- `n`: Number of elements in vectors x and y; must be a multiple of 4.
- `x`: A vector array of float values.
- `y`: A second vector array of float values.

## Discussion

Discussion The elements of x are copied to the corresponding elements of y.
