```c
SHZ_INLINE shz_quat_t shz_mat4x4_to_quat(const shz_mat4x4_t* mat) SHZ_NOEXCEPT;
```

Converts the given 4x4 orientation matrix into a quaternion.

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `mat` | `const shz_mat4x4_t *` |  |

## Returns

`shz_quat_t`

## Naming and requirements

- `shz_mat4x4_t` and `shz_mat2x2_t` arguments must be 8-byte aligned. Unaligned data goes through the `float[16]` parameters of the `_unaligned` routines.
