    how to do the matrix 5x5..i already have the non diagonal.but,how to get the diagonal

    Code:
    #include "stdafx.h"
    #include <iostream>
    #include <fstream>
    #include <string>
    #include <complex>
    #include <vector>
    #include <algorithm>
    using namespace std;
    
    
    
    int main()
    {
    int a,b,nbr=0,nbus;
    float c,d,e;
    vector<int> nl;
    vector<int> nr;
    vector<float> R;
    vector<float> X;
    vector<float> Bc;
    complex<float>* Z=NULL;
    complex<float>* y=NULL;
    vector<vector<complex<float>>> ybus;
    
    // First, get the number of line
    ifstream mydata("load flow.txt");
    string t3;
    nbr=0;
    while ( !mydata.eof())
    {
    while(getline(mydata, t3, '\n'))
    ++nbr;
    }mydata.close();
    // then read and get all the data in power flow data.txt
    ifstream input ("load flow.txt");
    for(int w=0;w<nbr;++w)
    {
    input >> a >>b >> c >>d >> e;
    nl.push_back(a);
    nr.push_back(b);
    R.push_back(c);
    X.push_back(d);
    Bc.push_back(e);
    
    cout<< a <<'\t' << b <<'\t'<< c <<'\t'<< d <<'\t'<< e<<'\t' <<endl;
    
    complex <double> Z( c , d );
    cout << "Z = " << Z << endl;
    complex <double> y=1./Z;
    cout<<y<<endl;
    
    
    
    
    }mydata.close();
    
    return 0;
    }

    my data is:
    1 2 0.02 0.06 0.03
    1 4 0.08 0.24 0.025
    2 4 0.06 0.24 0.020
    2 3 0.06 0.18 0.020
    3 4 0.04 0.12 0.010
    3 5 0.01 0.03 0.015
    4 5 0.08 0.24 0.025
