# GLKMatrix3Scale(_:_:_:_:)

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

## Declaration

```swift
func GLKMatrix3Scale(_ matrix: GLKMatrix3, _ sx: Float, _ sy: Float, _ sz: Float) -> GLKMatrix3
```

## Parameters

- `matrix`: The source matrix.
- `sx`: The amount to scale the x component.
- `sy`: The amount to scale the y component.
- `sz`: The amount to scale the z component.

## Return Value
