I have a Sparse matrix builded with vectors(vector<vector<int>>)

When I tried to multiply a scalar with matrix, the operator do correctly the operations, but when it returns the value, it returns an empty matrix.
This is the operator * :

MatriuSparse MatriuSparse::operator*(float s) {

    MatriuSparse aux;

    aux.matriu = matriu;

    aux.m_Nlinies = m_Nlinies;

    aux.m_Ncolumnes = m_Ncolumnes;

    for (int i = 0; i < m_Nlinies; i++) {

        for (int j = 0; j < m_Ncolumnes; j++) {

            aux.matriu[i][j] *= s;

        }

    }

    return aux;

}

This is the destructor:

MatriuSparse::~MatriuSparse() {

    matriu.clear();

}

This is the copy constructor:

MatriuSparse::MatriuSparse(const MatriuSparse& m) {



    m_Nlinies = m.m_Nlinies;

    m_Ncolumnes = m.m_Ncolumnes;

    m_valor = m.m_valor;

    matriu = m.matriu;

    for (int i = 0; i < m_Nlinies; i++) {

        for (int j = 0; j < m_Ncolumnes; j++) {

            matriu[i][j] = m.matriu[i][j];

        }

    }



}

In the main I call the operator in this form:

MatriuSparse m1(nomFitxer); //Constructor call.

MatriuSparse mProdX1 = m1 * 6;
