Suma de matrices

[Madelaine]

Podrian ayudarme a encontrer que está mal en el código por favor, al momento de copilar no salen errores pero cuando lo ejecuto no sale nada en la funcion que suma las matrices.


#include<iostream>
#include<cmath>
#include<vector>
#include<stdlib.h>
#include<time.h>

void imprima_vector (std::vector <double> );
void imprima_matriz (std::vector<std::vector<double> > );
std::vector<std::vector<double> > suma_matrices (std::vector<std::vector<double> > ,std::vector<std::vector<double> > );
void llenar_aleatorio(std::vector<std::vector<double> >& , int ,int );

int main()
{
using namespace std;
int n=4, m=3;
vector<vector<double> > A(n),B(n) ;

A.resize(n);

for( int i=0; i<A.size () ;i++)
A[i].resize(m);

llenar_aleatorio(A,-9,0);
imprima_matriz(A);
cout<<endl;
B.resize(n);

for( int i=0; i<B.size () ;i++)
B[i].resize(m);
llenar_aleatorio(B,1,9);
imprima_matriz(B);

imprima_matriz(suma_matrices(A,B));




}

A[i][j];

for (int i=0; i<A.size();i++)
imprima_vector (A[i]);
}

void llenar_aleatorio(std::vector<std::vector<double> >& Y, int p,int q)
{
srand(time(NULL));
for(int i=0; i<Y.size();i++)
for(int j=0;j<Y[i].size();j++)
Y[i][j]=rand()%(q-p-1)+p;
}

std::vector<std::vector<double> > suma_matrices (std::vector<std::vector<double> > A,std::vector<std::vector<double> > B)
{

return S;
