C Language Example - Matrix Transposition
Matrix transpose.
Example
#include <stdio.h>
int main()
{
int a[10][10], transpose[10][10], r, c, i, j;
printf("Enter the number of rows and columns of the matrix:");
scanf("%d %d", &r, &c);
// Store matrix elements
printf("\nEnter matrix elements:\n");
for(i=0; i<r; ++i)
for(j=0; j<c; ++j)
{
printf("Enter element a%d%d:",i+1, j+1);
scanf("%d", &a[i][j]);
}
// Display matrix a[][] */
printf("\nEnter matrix:\n");
for(i=0; i<r; ++i)
for(j=0; j<c; ++j)
{
printf("%d ", a[i][j]);
if (j == c-1)
printf("\n\n");
}
// Transpose
for(i=0; i<r; ++i)
for(j=0; j<c; ++j)
{
transpose[j][i] = a[i][j];
}
// Display the transposed matrix a
printf("\nMatrix after conversion:\n");
for(i=0; i<c; ++i)
for(j=0; j<r; ++j)
{
printf("%d ",transpose[i][j]);
if(j==r-1)
printf("\n\n");
}
return 0;
}
The output result is:
输入矩阵的行与列: 2 3 输入矩阵元素: 输入元素 a11: 2 输入元素 a12: 3 输入元素 a13: 4 输入元素 a21: 5 输入元素 a22: 6 输入元素 a23: 4 输入矩阵: 2 3 4 5 6 4 转换后矩阵: 2 5 3 6 4 4other extensions
