> Multiplies and accumulates mat by a 3D rotation matrix about the Z axis

```c
SHZ_INLINE void shz_mat4x4_rotate_z(shz_mat4x4_t* mat, float radians) SHZ_NOEXCEPT;
```

Multiplies and accumulates `mat` by a 3D rotation matrix about the Z axis.

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `mat` | `shz_mat4x4_t *` |  |
| `radians` | `float` |  |

## Returns

Nothing (`void`).

## Warnings

- This routine clobbers XMTRX.

## 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.
