Find trace of matrix formed by adding Row-major and Column-major order of same matrix in C++
In this tutorial, we will be discussing a program to find trace of matrix formed by adding Row-major and Column-major order of same matrix.
For this we will be provided with two arrays one in row-major and other in columnmajor. Our task is to find the trace of the matrix formed by the addition of the two given matrices.
Example
#include <bits/stdc++.h>
using namespace std;
//calculating the calculateMatrixTrace of the new matrix
int calculateMatrixTrace(int row, int column) {
int A[row][column], B[row][column], C[row][column];
int count = 1;
for (int i = 0; i < row; i++)
for (int j = 0; j < column; j++) {
A[i][j] = count;
count++;
}
count = 1;
for (int i = 0; i < row; i++)
for (int j = 0; j < column; j++) {
B[j][i] = count;
count++;
}
for (int i = 0; i < row; i++)
for (int j = 0; j < column; j++)
C[i][j] = A[i][j] + B[i][j];
int sum = 0;
for (int i = 0; i < row; i++)
for (int j = 0; j < column; j++)
if (i == j)
sum += C[i][j];
return sum;
}
int main() {
int ROW = 6, COLUMN = 9;
cout << calculateMatrixTrace(ROW, COLUMN) << endl;
return 0;
}Output
