# init(_:)

Creates a scaled pose with the specified single-precision 4 x 4 matrix

```
init?(_ matrix: simd_float4x4)
```

## Parameters

`matrix`

The source matrix

## Discussion> note: This function can’t extract rotation from a non-scale-rotate-translate affine transform. In that case,
> the function returns `nil`.  If the specified matrix doesn’t have uniform scale the function returns `nil`.
