# GLKMatrix3ScaleWithVector4(_:_:)

Returns a new 3x3 matrix created by concatenating a matrix with a scaling transform defined by a vector.

## Declaration

```swift
func GLKMatrix3ScaleWithVector4(_ matrix: GLKMatrix3, _ scaleVector: GLKVector4) -> GLKMatrix3
```

## Parameters

- `matrix`: The source matrix.
- `scaleVector`: A vector whose x, y and z components are used to scale the matrix.

## Return Value

Return Value A new matrix.
