c++ - combine variables in a vector/matrix -

i regular matlab user new c++. appreciate if 1 me solve problem.

i have few variables , vectors. say

#include<iostream> #include<vector> int main(){ int a=1; int b=1; vector<int> v1(100,0); vector<int> v2(100,0);  return 0; } 

i want combine variables (a,b,v1,v2) in 2x101 matrix (say m) first , second rows of m are

m[0] = {a,v1}; m[1] = {v2,b}; 

how define m , assign variables? appreciated.

if want ability insert in front or @ should use std::deque. following

deque<deque<int>> m; m.push_back(v1); m.push_front(a); m.push_back(v2); m[1].push_back(b); 

this create 2 dimensional array or matrix 2 vectors rows.

or create 2 dimensional vector , fill in elements manually

vector<vector<int>> m; m.resize(2);  // reserve space efficiency reasons, prevents reallocation m[0].reserve(v1.size() + 1); m[0].push_back(a); (auto integer : v1) {     m[0].push_back(integer); }  m[1].reserve(v2.size() + 1); (auto integer : v2) {     m[1].push_back(integer); } m[1].push_back(b);
