三元组矩阵的转置java

以下是三元组矩阵的转置Java代码示例：

public class SparseMatrix {
    public static void main(String[] args) {
        int[][] matrix = {{0, 0, 3, 0, 4}, {0, 0, 5, 7, 0}, {0, 0, 0, 0, 0}, {0, 2, 6, 0, 0}};
        int row = matrix.length;
        int col = matrix[0].length;
        int count = 0;
        for (int i = 0; i < row; i++) {
            for (int j = 0; j < col; j++) {
                if (matrix[i][j] != 0) {
                    count++;
                }
            }
        }
        Triple[] data = new Triple[count + 1];
        data[0] = new Triple(row, col, count);
        int index = 1;
        for (int i = 0; i < row; i++) {
            for (int j = 0; j < col; j++) {
                if (matrix[i][j] != 0) {
                    data[index] = new Triple(i, j, matrix[i][j]);
