day30 --------------------------------------------------------------- 实例044:矩阵相加 题目 计算两个矩阵相加. 分析:矩阵可以看成是二维列表,外围列表指的就是矩阵的行,里面的列表就是对应的列,即a[1][2]代表第一行第二列. def Matrix(col,row): list = [] if col or row: for i in range(1,row+1): list2 = [] for j in range(1
举个栗子: # 两个 3 行 3 列的矩阵,实现其对应位置的数据相加,并返回一个新矩阵: # 使用 for 迭代并取出 X 和 Y 矩阵中对应位置的值,相加后放到新矩阵的对应位置中. import numpy as np a = np.random.randint(1,100,(3,3)) print(a) b = np.random.randint(1,100,(3,3)) print(b) Z =np.zeros(shape=(len(a),len(a[0]))) print(Z) for
#include<stdio.h> #include<stdlib.h> #include<time.h> #include<string.h> void main() { int a[4][4]; int b[4][4]; int c[4][4]; int i,j,k,s,t,m,n; srand(time(0)); for(i=0;i<=3;i++) for(j=0;j<=3;j
1.矩阵相加 两个同型矩阵做加法,就是对应的元素相加. #include<iostream> using namespace std; int main(){ int a[3][3]={{1,2,3},{6,5,4},{4,3,2}}; int b[3][3]={{4,3,2},{6,5,4},{1,2,3}}; int c[3][3]={0,0,0,0,0,0,0,0,0}; int i,j; cout<<"Array A:"<<endl; for
测量平差以及工科中常常用到矩阵的相关运算,因此自己写了一个,同时考虑到了类库的可用性,这次又重载了比较匀运算符,修正了一些问题 using System; using System.Collections.Generic; namespace CMath { [Serializable] public class Matrix { public double[] element; ; ; /// <summary> /// 获取矩阵行数 /// </summary> public
