我怎么... C ++ [英] How do I.. C++
问题描述
我想写一个关于4x4矩阵的代码。乘法，加法，行列式，等级，辅助因子等我想用类和函数创建程序。代码将类似于段落
定义一个名为multipication_matrices的函数，它接收两个矩阵数据并返回这两个矩阵的乘法值。 multipication_matrices返回的值应该由在类结果中声明的属性mult保存。
感谢您的帮助...
< b>我尝试了什么：
i want to write a code about 4x4 matrix. multiplication,add,determinant,rank,cofactor etc. i want to create the programme with class and function. the code will be as like the paragraph
""Define a function called multipication_matrices which received two matrices data and returns the multipication value of these two matrices. The value returned by multipication_matrices should be kept by attribute mult which declared in class result.""
Thanks for help...
What I have tried:
#include<iostream>
using namespace std;
class result {
public:
float a[10][10],b[10][10],mlt[10][10],i,j;
int multipication_matrices()
{
int i,j,k,result,mlt[10][10],mult;
for(i = 0; i < 4; ++i)
for(j = 0; j < 4; ++j)
for(k = 0; k < 4; ++k)
{
result = mlt[i][j] += a[i][k] * b[k][j];
}
return result;}
}r;
int main()
{
int i,j,k,result,a[10][10],b[10][10],mlt[10][10],mult;
cout << "Enter elements of matrix 1:" << endl;
for(i = 0; i < 4; ++i)
for(j = 0; j < 4; ++j)
{
cout << "Enter element a" << i + 1 << j + 1 << " : ";
cin >> a[i][j];
}
// Storing elements of second matrix.
cout << "Enter elements of matrix 2:" << endl;
for(i = 0; i < 4; ++i)
for(j = 0; j < 4; ++j)
{
cout << "Enter element b" << i + 1 << j + 1 << " : ";
cin >> b[i][j];
}
cout << endl << "Output Matrix: " << r.multipication_matrices() << endl;
for(i = 0; i < 4; ++i)
for(j = 0; j < 4; ++j)
{
cout << " " << result;
if(j == 4-1)
cout << endl;
}
return 0;
}
推荐答案
乘法：使用多维数组乘以两个矩阵的C ++程序 [ ^ ]
另外：使用多维数组添加两个矩阵的C ++程序 [ ^ ]
行列式：矩阵行列式算法C ++ - Stack Overflow [ ^ ]
等等。另外你会发现我找到了上面的那个Google;）
multiplication: C++ Program to Multiply Two Matrix Using Multi-dimensional Arrays[^]
addition: C++ Program to Add Two Matrix Using Multi-dimensional Arrays[^]
determinant: Matrix determinant algorithm C++ - Stack Overflow[^]
etc. etc. The other you will find like I found the one above with Google ;)
我如何... C ++
How do I.. C++
有一些工作，学习和研究。
所以，你没有尝试自己解决问题，你毫无疑问，你只想要我们做你的家庭作业。
家庭工作问题是你在现实生活中必须解决的问题的简化版本，他们的目的是学习和练习。
With some work, study and research.
So, you show no attempt to solve the problem yourself, you have no question, you just want us to do your HomeWork.
HomeWork problems are simplified versions of the kind of problems you will have to solve in real life, their purpose is learning and practicing.
我想写一个关于4x4矩阵的代码。
i want to write a code about 4x4 matrix.
找到数学并开始工作。
我们不做你的HomeWork。
HomeWork我们不会在乞求其他人做你的工作时测试你的技能，它会让你思考并帮助你的老师检查你对你所学课程的理解以及你应用它们时遇到的问题。
你的任何失败都会帮助你的老师发现你的弱点并设定补救措施。
你的任何失败都会帮助你了解什么有效，什么无效，被称为'试错'学习。
所以，试一试，重读课程并开始工作。如果您遇到特定问题，请显示您的代码并解释这个问题，我们可能会提供帮助。
作为程序员，您的工作是创建算法解决特定问题，你不能依赖别人永远为你做，所以有一段时间你必须学会如何。而且越快越好。
当你要求解决方案时，就像试图通过培训其他人来学习开车一样。
创建算法基本上是找到数学并做出必要的调整以适应你的实际问题。
Find the maths and start to work.
We do not do your HomeWork.
HomeWork is not set to test your skills at begging other people to do your work, it is set to make you think and to help your teacher to check your understanding of the courses you have taken and also the problems you have at applying them.
Any failure of you will help your teacher spot your weaknesses and set remedial actions.
Any failure of you will help you to learn what works and what don't, it is called 'trial and error' learning.
So, give it a try, reread your lessons and start working. If you are stuck on a specific problem, show your code and explain this exact problem, we might help.
As programmer, your job is to create algorithms that solve specific problems and you can't rely on someone else to eternally do it for you, so there is a time where you will have to learn how to. And the sooner, the better.
When you just ask for the solution, it is like trying to learn to drive a car by having someone else training.
Creating an algorithm is basically finding the maths and make necessary adaptation to fit your actual problem.
