Equality of two DenseMatrix objects

[Tharindu Rusira]

Hi all,
what are the necessary conditions for two matrices (DenseMatrix) to be
equal and how to check equality?
I tried the following code with *boolean java.lang.Object.equals(Object
obj)* method but it always returns *false*.

        DenseMatrix m1 = new DenseMatrix(3, 3);
        m1.assign(new double[][]{{1,2,3},{4,5,6},{7,8,9}});
        DenseMatrix m2 = new DenseMatrix(3, 3);
        m2.assign(new double[][]{{1,2,3},{4,5,6},{7,8,9}});
        if(m1.equals(m2)){
            System.out.println("m1 = m2");
        }else{
            System.out.println("m1 != m2");
        }


However, *m1.asFormatString().equals(m2.asFormatString())*
 returns true. Is there a more rigorous 
way of checking this equality (of values and dimensions)
 without converting the matrices to Strings?

Thanks,
