# 23 Oct 2020 Find the inverse of a Matrix in MATLAB, is inv(A) or A\eye(size(A)) more precise? RST Published at Dev. 3. rst. The title explains it already.

역행렬(Matrix Inverse) MATLAB inv 함수는 X가 준특이 행렬(badly scaled)이거나 유사 특이 행렬(nearly singular)이면 경고를 출력합니다.

The inverse would be an ugly looking matrix with lots of terms in it. Try to use simplify or something on terms to make it easier to read. Or sometimes I paste it in a text editor and manually simplify it myself. for example I go and using find and replace that exists in every editor I say for example replace every a11*a22-a12*a21 by T1 and so on. I have a 4x3 matrix(S) and i want to calculate the inverse of it, the matrix is: S= Find the treasures in MATLAB Central and discover how the community can help you!

For instance, if the matrix is called "A," type "inv(A)." Get the answer. The inverse of A appears on the screen, and the process is complete. If MATLAB outputs an error message, it may be necessary to troubleshot.

If the matrix A does not have full rank, there is no inverse. In consequence you cannot find any B, which satisfies A*B=eye . This is the definition of the rank, of invertible and there cannot be an "alternative". This means, that the question is not meaningful.
