> Extracts the col index as a 4D column vector from the given matrix

```c
SHZ_INLINE shz_vec4_t shz_mat4x4_col(const shz_mat4x4_t* mat, size_t col) SHZ_NOEXCEPT;
```

Extracts the `col` index as a 4D column vector from the given matrix.

## Parameters

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

## Returns

`shz_vec4_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.
