Source: https://sh4zam.com/api/xmtrx/shz_xmtrx_load_wxyz_4x4/

```c
SHZ_INLINE void shz_xmtrx_load_wxyz_4x4(const shz_mat4x4_t* matrix) SHZ_NOEXCEPT;
```

Loads the given 4x4 matrix as XMTRX, with the 4th column for translation being loaded as the first column.

## Parameters

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

## Returns

Nothing (`void`).

## Naming and requirements

- `_wxyz`: Register/column permutation so that `FTRV` yields W first (cycle 4 instead of 7), which helps perspective division. ([Naming and Suffixes](https://sh4zam.com/concepts/naming-and-suffixes/))
- `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.
