Take a two dimensional array inside class as private member. Initilialise it in constructor. The use a method as setValue() which changes the value of array using the formula you gave using two for loops.

i writing this codings ,but it seems that the scalar doesn't work. The elements of matrix are still 1. does any one know the problem?>

//////////////////////////////////////////////////////////////////
Matrix::Matrix()
{
for (int i = 0; i < 3; i++)
for (int j = 0; j < 3; j++)
M[i][j] = 1;
}


// operator functions


Matrix Matrix::operator*( double aij )
{
Matrix temp;
int i, j;
for(i=1; i <= 3; i++)
for(j=1; j <= 3; j++)
aij = (i*j)/(i+j-1);
temp.M[i][j] = aij* M[i][j];

return temp;
}
