MATLAB Matrix Inverse - Learn how to calculate the inverse of a matrix in MATLAB with step-by-step examples and explanations.
If you need to calculate the dot product of A and B, you need to use the notation A*B to do the calculation, this calculation process is the same as what we learned in linear algebra, as shown below: 5. 矩阵对应数值相乘(Multiply the corresponding values of the matrix) 矩阵对应数值相乘...

当矩阵A*B=B*A=I时,我们称B是A的逆矩阵(Inverse Matrix),记作B=A^-1,而A则被称为可逆矩阵。逆矩阵有点类似于倒数。行数和列数相等的矩阵称为方阵(Square Matrix),逆矩阵和可逆矩阵都是方阵。数字0没有倒数,同理许多矩阵也没有逆矩阵,非方阵的矩阵就是不可逆的。逆矩阵求法:A^(-1)=(1/|A|)×...
This means that the matrix will introduce large errors when you do any kind of calculations with it, such as an inverse. I found this which might help you:http://www.mathworks.se/matlabcentral/newsreader/view_thread/67650In the link, they mention the use ...
