C++将short数组存储为matlab mat文件

在C++中,若想将`short`类型的数组保存为MATLAB的.mat文件,你需要借助第三方库,如`MatlabIO`或`HDF5`,因为MATLAB的内置函数并不直接支持C++。
首先,安装相应的库,例如`libsvm-matlab-bindings`或`hdf5`,然后你可以按照以下步骤操作:
1. 包含必要的头文件和初始化库:
```cpp
#include <iostream>
#include <vector>
#include "matlabio.h" // 或者 "hdf5.h"
```
2. 创建并填充short数组:
```cpp
std::vector<short> shortArray;
// ... (填充数组内容)
// 确保数组长度为矩阵维度所需
const int rows = /* your array length */;
const int cols = 1; // 假设单列矩阵
```
3. 将数组转换为MAT文件:
```cpp
try {
mxArray *matrix = mxCreateDoubleMatrix(rows, cols, mxREAL); // 使用double矩阵,因为MATLAB读取的是浮点数
for (int i = 0; i < rows; ++i) {
matrix[i] = static_cast<double>(shortArray[i]);
}
mexCallMATLAB(1, &matrix, "arrayName", mxArrayClassID, mxArrays); // 如果是matlabio,使用这个函数;如果是hdf5则需要其他对应操作
// 写入文件
mxArrayWriteToMatlab("output.mat", matrix);
std::cout << "Short array saved to output.mat." << std::endl;
} catch (std::exception& e) {
std::cerr << "Error writing to MATLAB file: " << e.what() << std::endl;
}
```
