# Matrix3::operator* (Vector3)

```cpp
Vector3 operator*(const Vector3& v) const
```

矩阵-向量乘法运算，将矩阵应用于向量。

**参数：**
- `v` - 三维向量

**返回：** `Vector3` - 变换后的向量

**复杂度：** O(1)

**示例：**

```cpp
Matrix3 rotation = Matrix3::RotationZ(Math::Radians(90.0f));
Vector3 v(1.0f, 0.0f, 0.0f);

Vector3 rotated = rotation * v;
// 结果: approximately (0, 1, 0)
```
