inverse matrix definition In linear algebra a minor of a matrix A is the determinant of some smaller square matrix cut down from A by removing one or more of its rows or columns From Minor linear algebra So your friend is right The minor of a matrix is a number not a matrix EDIT You re also right about the inverse of a matrix Share
There are really three possible issues here so I m going to try to deal with the question comprehensively First since most others are assuming this I will start with the definition of an inverse mat Given a square matrix is the transpose of the inverse equal to the inverse of the transpose A 1 T A T 1

9 begingroup From what I understand the inverse of a matrix only exists if the matrix is square I recently learned however that the inverse of a quaternion is the quaternion vector 1xn dimensions where each element has been divided by the length of the vector squared 1 You start with a supposedly real world example and then let us suppose three hypothetical species only sequentially depending on each other which is not the real world Therefore it is a tricky business to define what is real or not in these Modeling problems I wouldn t attach tags to problems as such if I were you
I will give a basic definition understanding one that I learned in introductory Linear Algebra For a matrix A A the inverse matrix A 1 A 1 is a matrix that when multiplied by A A yields the Identity matrix of the vector space AA 1 I A A 1 I A 1 A 1 can be multiplied to the left or right of A and still yield I I It happens that a square matrix has a left inverse iff it has a right inverse iff it has an inverse but this isn t true in more general contexts Yes keeping in mind the restriction to square matrices An invertible matrix is a matrix with an inverse It s a theorem that this is equivalent to having a nonzero determinant for a square matrix

begingroup AbhishekBhatia Because the inverse of a diagonal matrix with non zero entries is the diagonal matrix of the reciprocals endgroup Jonathan H Commented Mar 8 2018 at 11 33 0 Inverse and Invertible does not mean the same Matrix An n A n n is Invertible when is non singular or regular this is det A 0 det A 0 and rank A n r a n k A n This means that each column of A A is not a linear combination of the rest so A has full rank and non zero determinant therefore it s regular or non
