```
struct simd_half3x4
```

## Topics

### Initializers

[`init()`](/documentation/simd/simd_half3x4/init())

Creates a new matrix with uninitialized memory.

[`init(columns:)`](/documentation/simd/simd_half3x4/init(columns:))

Creates a new matrix with the specified columns.

### Matrix properties

[`columns`](/documentation/simd/simd_half3x4/columns)

The columns of the matrix.

### Matrix creation functions

[`simd_matrix(_:_:_:)`](/documentation/simd/simd_matrix(_:_:_:)-5oh9m)

Returns a new matrix with the specified columns.

[`simd_matrix_from_rows(_:_:_:_:)`](/documentation/simd/simd_matrix_from_rows(_:_:_:_:)-9v9ky)
