使用c指针转置矩阵，内存访问错误

#include <stdio.h>
#include <stdlib.h>

void transposeMatrix(int** matrix, int rows, int cols) {
    int** transposed = (int**)malloc(cols * sizeof(int*));
    for (int i = 0; i < cols; i++) {
        transposed[i] = (int*)malloc(rows * sizeof(int));
        for (int j = 0; j < rows; j++) {
            transposed[i][j] = matrix[j][i];
        }
    }

    // 打印转置后的矩阵
    for (int i = 0; i < cols; i++) {
        for (int j = 0; j < rows; j++) {
            printf("%d ", transposed[i][j]);
        }
        printf("\n");
    }

    // 释放内存
    for (int i = 0; i < cols; i++) {
        free(transposed[i]);
    }
    free(transposed);
}

int main() {
    int rows = 3;
    int cols = 4;

    int** matrix = (int**)malloc(rows * sizeof(int*));
    for (int i = 0; i < rows; i++) {
        matrix[i] = (int*)malloc(cols * sizeof(int));
        for (int j = 0; j < cols; j++) {
            matrix[i][j] = i * cols + j + 1;
        }
    }

    transposeMatrix(matrix, rows, cols);

    // 释放内存
    for (int i = 0; i < rows; i++) {
        free(matrix[i]);
    }
    free(matrix);

    return 0;
