请问哪位高手可以帮我做一道关于向量的题目,
可是我有困难,(题目如下)(中英文)
suppose you know that the 3 by 4 matrix A has the vector S=(2,3,1,0) as the only special solution to Ax=0.
(a) What is the rank of A and the complete solution to Ax=0
(b) What is the exact row reduced echelon form Rof
(c) How do you know that Ax=b can be solved for all
假设你知道一个3排4列的的矩阵A只有一个Ax=0的特别解法 S=(2,3,1,0)
(a)A的rank是什么,求出Ax=0的complete solution
(b) 求出A的最简梯形形式R
(C) 你怎么知道Ax=b 对所有b都有解
这个就是问题了,下周就要用了,
