有哪位会使用matlab软件的高手们，帮帮忙啊，就是计算矩阵之间的乘法，具体求助有关矩阵X乘以(1-X)的逆矩阵的运算,matlab里是不是不能运算有小数点的逆矩阵啊 我运行时怎么老出错误啊，提示出“Matrix must be square”，望各位再帮帮忙啊

X是个什么矩阵你没说呀，没法写呀 1# yangjinglove201

首先让matlab告诉你这个X的维度
比方：
[m,n]=size(X);
在知道X的行列数（m，n）后，
定义一个单位阵，和X有相同的维度

因为有inverse matrix，其实说明
m=n啦

最后
X * inverse(I-X)

X * inv ( I - X )

2# nkzxl
是一个一般的矩阵比较大  是17阶的一个矩阵 需要矩阵告诉你才能计算吗 因为我不太懂这个 所以也不知道怎么办

3# 海桐浪迹
方便QQ联系吗？我的QQ：542716952，有空的话加我，帮我算算这个矩阵啊
