复制代码 代码如下:

public interface IMatrixMultiple {

public int[][] mmltiple(int[][]a ,int [][]b);

}

?public class MatrixMultiple implements IMatrixMultiple {

@Override

public int[][] mmltiple(int[][] a, int[][] b) {

int [][] result = new int[a.length][b[0].length];

for (int i = 0; i<a.length; i++) {

for (int j = 0; j<b[0].length; j++) {

for (int k = 0; k<a[0].length; k++) {

result[i][j]= result[i][j]+a[i][k]*b[k][j];

}

}

}

return result;

}

}
