矩阵镜像翻转是矩阵操纵中的一个罕见任务,它涉及将矩阵沿某条轴停止翻转。在C言语编程中,实现矩阵镜像翻转是一个基本且实用的技能。本文将具体介绍如何在C言语中实现矩阵的高低翻转、阁下翻转以及顺时针扭转90度,并分享一些编程技能。
矩阵镜像翻转重要有以下多少种情势:
#include <stdio.h>
void flipUpAndDown(int rows, int cols, int matrix[rows][cols]) {
for (int i = 0; i < rows / 2; i++) {
for (int j = 0; j < cols; j++) {
int temp = matrix[i][j];
matrix[i][j] = matrix[rows - 1 - i][j];
matrix[rows - 1 - i][j] = temp;
}
}
}
void printMatrix(int rows, int cols, int matrix[rows][cols]) {
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols; j++) {
printf("%d ", matrix[i][j]);
}
printf("\n");
}
}
int main() {
int rows = 4, cols = 5;
int matrix[4][5] = {
{1, 2, 3, 4, 5},
{6, 7, 8, 9, 10},
{11, 12, 13, 14, 15},
{16, 17, 18, 19, 20}
};
printf("Original Matrix:\n");
printMatrix(rows, cols, matrix);
flipUpAndDown(rows, cols, matrix);
printf("Flipped Matrix (Up and Down):\n");
printMatrix(rows, cols, matrix);
return 0;
}
void flipLeftAndRight(int rows, int cols, int matrix[rows][cols]) {
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols / 2; j++) {
int temp = matrix[i][j];
matrix[i][j] = matrix[i][cols - 1 - j];
matrix[i][cols - 1 - j] = temp;
}
}
}
void rotate90Clockwise(int rows, int cols, int matrix[rows][cols]) {
for (int i = 0; i < rows; i++) {
for (int j = i; j < cols; j++) {
int temp = matrix[i][j];
matrix[i][j] = matrix[j][i];
matrix[j][i] = temp;
}
}
for (int i = 0; i < rows; i++) {
for (int j = 0; j < cols / 2; j++) {
int temp = matrix[i][j];
matrix[i][j] = matrix[i][cols - 1 - j];
matrix[i][cols - 1 - j] = temp;
}
}
}
经由过程以上方法,你可能在C言语中轻松实现矩阵的镜像翻转。这些技能不只实用于矩阵操纵,还可能扩大年夜到其他数据处理任务中。
