# Matrix4x4::Inverse
|
|
|
|
```cpp
|
|
Matrix4x4 Inverse() const
|
|
```
|
|
|
|
返回矩阵的逆矩阵。如果矩阵的行列式接近零（不可逆），则返回单位矩阵。
|
|
|
|
**参数：** （无）
|
|
|
|
**返回：** 逆矩阵；如果矩阵不可逆则返回单位矩阵
|
|
|
|
**线程安全：** ✅
|
|
|
|
**复杂度：** O(n³)，对于 4x4 矩阵固定为 64 次基本运算
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include "XCEngine/Core/Math/Matrix4.h"
|
|
|
|
using namespace XCEngine::Math;
|
|
|
|
Matrix4 transform = Matrix4::TRS(
|
|
Vector3(1.0f, 2.0f, 3.0f),
|
|
Quaternion::FromEuler(0.0f, 45.0f, 0.0f),
|
|
Vector3(2.0f, 2.0f, 2.0f)
|
|
);
|
|
|
|
Matrix4 inv = transform.Inverse();
|
|
Matrix4 identity = transform * inv;
|
|
// identity 接近单位矩阵
|
|
```
