        double a[][] = {
            {0., 1., 2., 3.},

        //	Construct a PrintMatrix object with a title
        PrintMatrix p = new PrintMatrix("A Simple Matrix");
        
        //	Print the matrix
        p.print(a);
        
        //	Turn row and column labels off
        PrintMatrixFormat mf = new PrintMatrixFormat();
        mf.setNoRowLabels();
