算法 - 矩阵乘法

JAVA实现矩阵乘法运算

public static int[][] multiplyMatrix(int[][] a, int[][] b) {    int m = a.length;    int n = b[0].length;    int s = a[0].length;    int[][] ans = new int[m][n];    for (int i=0; i<m; i++) {        for (int j=0; j<n; j++) {            for (int k=0; k<s; k++) {                ans[i][j] += a[i][k] * b[k][j];            }        }    }    return ans;}
