> Sets the values of mat at the given row to those of the 4D vector, vec

```c
SHZ_INLINE void shz_mat4x4_set_row(shz_mat4x4_t* mat, size_t row, shz_vec4_t vec) SHZ_NOEXCEPT;
```

Sets the values of `mat` at the given `row` to those of the 4D vector, `vec`.

## Parameters

| Name | Type | Description |
| --- | --- | --- |
| `mat` | `shz_mat4x4_t *` |  |
| `row` | `size_t` |  |
| `vec` | `shz_vec4_t` |  |

## Returns

Nothing (`void`).

## 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.
