EX1

void matrixbase_SumRows_ex1()
{
    int rc, ii,jj;
    matrix<double> mat = {
        {-1,  0,  3,  99},
        { 0,  2,  6,   0},
        { 1,  4,  9,   0}
    };
    mat[0][3]=NANUM;
        
    vector vRSum;
    int nRet = mat.SumRows(vRSum);
}

Remark

Sum the rows of this matrix placing the result in a vector. The underlying base type of the vector must not be less than the underlying base type of the matrix.
