+# Matrix4::Decompose
+
+```cpp
+void Decompose(Vector3& translation, Quaternion& rotation, Vector3& scale) const
+```
+
+将矩阵分解为平移、旋转和缩放分量。
+
+**参数：**
+- `translation` - 输出平移向量
+- `rotation` - 输出旋转四元数
+- `scale` - 输出缩放向量
+
+**复杂度：** O(1)
+
+**示例：**
+
+```cpp
+Matrix4 m = ...;
+Vector3 translation;
+Quaternion rotation;
+Vector3 scale;
+m.Decompose(translation, rotation, scale);
+```
