兩個矩陣之間的算法

兩個矩陣之間的算法，，，用到了包 commons-math-2.2.jar

    public static void main(String[] args) {
        Matrix a = new Matrix();
        double[][] abc = {{1,2,3},{2,0,0},{1,1,1}};
        double[][] ab = {{1,2,3},{2,0,0},{1,1,1}};
        Array2DRowRealMatrix bca = new Array2DRowRealMatrix(abc);
        Array2DRowRealMatrix aba = new Array2DRowRealMatrix(ab);
        System.out.println(bca.add(aba));
        //System.out.println(bca.scalarMultiply(2));
    }
