java 矩阵统计计算

使用的是flanagan包

例子中的2个矩阵相乘

首先创建2个double类型的二维数组

用new Matrix(double[][]);构造吧二维数组转换成Matrix 利用times方法进行乘法

代码如下：

/**

package com.xin.test;

import flanagan.math.Matrix;

/**

public class Test {


	public static void main(String[] args) {
		double[][] arraysA = {{1,2,3,4,5,6}};
		double[][] arraysB = {{1,2,3,4,5},{1,2,3,4,5},{1,2,3,4,5},{1,2,3,4,5},{1,2,3,4,5},{1,2,3,4,5}};
		double[][] arraysC = new double[1][5];

		Matrix matrixA = new Matrix(arraysA);
        Matrix matrixB = new Matrix(arraysB);
        Matrix matrixC = new Matrix(1,5);
        matrixC = matrixA.times(matrixB);
        arraysC = matrixC.getArrayCopy();
        for(int i=0; i<1; i++){
            for(int j=0; j<5; j++){
                System.out.print(arraysC[i][j]+"/t");
            }
            System.out.println(" ");
        }
        System.out.println(" ");

	}
