请求Matlab高手帮忙,解一道矩阵题
请用matlab解答,给过程和结果,

Answer 1

启动matlab,在command window里面输入如下：
>>A=[16 2 3 13;5 11 10 8;9 7 6 12;4 14 15 1];
>>inv(A)
Warning:Matrix is close to singular or badly scaled.
Results may be inaccurate.RCOND = 1.306145e-017.
ans =
1.0e+014 *
0.9382 2.8147 -2.8147 -0.9382
2.8147 8.4442 -8.4442 -2.8147
-2.8147 -8.4442 8.4442 2.8147
-0.9382 -2.8147 2.8147 0.9382
这样就可以得出A的逆矩阵,不过你的矩阵给的有点问题,所以结果可能不精确.
