# Matrix4x4::operator[]
|
||
|
||
```cpp
|
||
float* operator[](int row)
|
||
const float* operator[](int row) const
|
||
```
|
||
|
||
通过行索引访问矩阵元素。返回指向该行第一列元素的指针。
|
||
|
||
**参数：**
|
||
- `row` - 行索引（0-3）
|
||
|
||
**返回：** 指向该行数据的指针
|
||
|
||
**线程安全：** ✅
|
||
|
||
**复杂度：** O(1)
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
#include "XCEngine/Core/Math/Matrix4.h"
|
||
|
||
using namespace XCEngine::Math;
|
||
|
||
Matrix4 m = Matrix4::Identity();
|
||
m[0][0] = 5.0f; // 设置第一行第一列
|
||
m[1][2] = 3.0f; // 设置第二行第三列
|
||
|
||
float val = m[0][1]; // 读取第一行第二列
|
||
```
