我为矩阵乘法编写了一个简单的 C++ 代码。该代码给出了 glib c 错误。将两个矩阵相乘是一个简单的矩阵乘法代码。
#include <iostream>
using std::cerr;
using std::cout;
using std::endl;
#include<stdio.h>
#include <string.h>
using std::string;
#include <fstream>
using std::ifstream;
using std::ofstream;
#include<stdlib.h>
#include<cmath>
#include<math.h>
#include<algorithm>
#include<cstdlib>
#include<ctime>
#include <vector>
using namespace std;
int main()
{
int i,j,k;
vector<int> mult;
vector<float> dist_shell;
std::string skip;
std::string empty_line;
std::string num_elements[3];
int cluster_num;
vector<int> inter_type; //Interaction type (2-2body;3-3body etc.)
int c_mult;
float c_dist_shell;
int c_inter_type; // c stands for cin type variables frm reading file
float unit_cell[3][3];
float factor;
int l,m,n;
float sum;
ifstream poscar("POSCAR");
float unit_cell[3][3];
int total_atom=32;
float frac[total_atom][3];
float real_pos[total_atom][3];
for (int count=0;count<total_atom;count++)
{
poscar>>frac[count][1]>>frac[count][2]>>frac[count][3]>>true_false[count][1]>>true_false[count][2]>>true_false[count][3];
}
for (l=0;l<total_atom;l++)
{
for (m=0;m<3;m++)
{
sum=0;
for (n=0;n<3;n++)
{
sum+=frac[l][n]*unit_cell[n][m];
}
real_pos[l][m]=sum;
}
}
return 0;
}
我的错误是：

我想弄清楚我的代码的另一部分是否有错误。更改数据类型也无济于事。感谢所有可以帮助我发现错误的人。谢谢。
