# GLKMatrix4MakePerspective(_:_:_:_:)

Returns a 4x4 perspective projection matrix.

## Declaration

```swift
func GLKMatrix4MakePerspective(_ fovyRadians: Float, _ aspect: Float, _ nearZ: Float, _ farZ: Float) -> GLKMatrix4
```

## Parameters

- `fovyRadians`: The angle of the vertical viewing area.
- `aspect`: The ratio between the horizontal and the vertical viewing area.
- `nearZ`: The near clipping distance. Must be positive.
- `farZ`: The far clipping distance. Must be positive and greater than the near distance.

## Return Value

Return Value A new projection matrix.
