pointers using boost::ublas::matrix

[sanann]

Hello,
Using boost matrix, implemented matrices to generate 2 sets of low pass and high pass filters. these wwere implemented as a function. now i need an the four filters as output from the function to use them for filtering. how do i get 4 outputs from the function? if i am supposed to use pointers how do i do that?

 using namespace std;

int FILTERS::filter(int width,int height)

{

    using namespace boost::numeric::ublas;
    using namespace boost;
    boost::tuple<float,float,float,float> lowpass(unsigned width, unsigned height);
    {
        return make_tuple(Low1,Low2,Low3,Low4);

    }
    boost::numeric::ublas::vector<double>W(width),H(height);
    scalar_matrix<double> Matrix(width,height);

    matrix<float> matrix1(width,height),matrix2(width,height),matrix3(width,height),Cood1(width,height),Cood2(width,height),Cood3(width,height),Cood4(width,height);


    matrix<float> Sum1(width,height),Sum2(width,height), Diff1(width,height),Diff2(width,height), Denom1(width,height),Denom2(width,height);


    matrix<float> Low1(width,height), Low2(width,height), Low3(width,height), Low4(width,height);


    matrix<float> fSum1(width,height),fSum2(width,height),fDenom1(width,height),fDenom2(width,height);


    matrix<float> high1(width,height), high2(width,height), high3(width,height), high4(width,height);
    matrix<std::complex<float> > High1(width,height), High2(width,height),High3(width,height),High4(width,height);

//generate filters
L1,L2,H1,H2
