Matlab的逆矩阵命令:pinv(a)、inv(a)或a^-1。为了避开某些不可逆导致的错误,我们一般使用伪逆矩阵(pseudo-inverse)的pinv命令。转置矩阵把矩阵的行变成列,列变成行,得到的新矩阵称为转置矩阵(Transpose Matrix),记作A'或A^T。如果A是m*n矩阵,B=A',那么B是n*m矩阵,Bij=Aji。Matlab求逆矩阵:a'。 无尽愿...
MATLAB中不是每个矩阵都有逆矩阵的,比如一个矩阵的行列式是零的话,则矩阵的逆就不存在,这样的矩阵是奇异的。 MATLAB中,逆矩阵的计算使用 inv 函数:逆矩阵A是inv(A). 详细例子 在MATLAB中建立一个脚本文件,并输入下面的代码: a = [ 1 2 3; 2 3 4; 1 2 5] inv(a) 运行该文件,显示以下结果: a =...
I am doing Matrix inversion (33 x 33 marix) and getting warning message like "matrix is badly scaled or singular " i need that matrix inversion what is the possible way to get the answer Please help me to solve this How to Get Best Site Performance Select the China site (in...
I have a square very sparse matrix A with a dimension 4000 by 4000, and I have its inverse InvA. Now a row in A changes which is called matrix A1, how can I quickly obtain the inverse of A1 making use of InvA? Thanks a lot. ...
If you want the matrix inverse of alpha, well that's impossible to actually find (you can do some funny things with pseudo inverses but they're not real inverses). If none of that is what you are looking for then you need to ask a new question and better define what it is you ar...
