使用visual studio 2013读取.mat文件

//read .mat from matlab
#include <iostream>
#include <mat.h>
#include<iomanip>
#include <fstream>
int main()
{
    MATFile *pmatFile = NULL;
    mxArray *pMxArray = NULL, *pMxArray_i = NULL;
    double *pMx_cell_i = NULL;
    //读入.MAT
    pmatFile = matOpen("D:/Program Files/MATLAB/R2014a/work/mywork/test_for_data/mydata.mat", "r");
    pMxArray = matGetVariable(pmatFile, "T");
    size_t M = mxGetM(pMxArray);
    size_t N = mxGetN(pMxArray);
    //std::cout << N;
    int num_of_cell{ (int)mxGetNumberOfElements(pMxArray) };
    std::cout << "the number of the CELL we have got for the T :" << num_of_cell << std::endl;
    int A[10];
    //Matrix<double> A(num_of_cell, 1);
    for (int i{ 0 }; i < num_of_cell; i++)
    {
        pMxArray_i = mxGetCell(pMxArray, i);
        int num_of_cell_i = (int)mxGetNumberOfElements(pMxArray_i);
        std::cout << "the number of the CELL " << i << " we have got for the T :" << num_of_cell_i << std::endl;
        double sum_i = 0;
        for (int j{ 0 }; j < num_of_cell_i; j++)
        {
            pMx_cell_i = mxGetPr(pMxArray_i);
            std::cout << std::setw(10) << *(pMx_cell_i + j);
            sum_i = sum_i + *(pMx_cell_i + j);//进行加和
        }
        std::cout << std::endl;
        std::cout << "sum " << i << " is " << sum_i << std::endl;
        A[i] = sum_i;
                //
    }
    //写到e:/data.TXT中 
    FILE *p;
    if ((p = fopen("e:\\data.txt", "wt")) != NULL)
    for (int i = 0; i<10; i++) 
        fprintf(p, "%d \n", A[i]);  
    fclose(p);
