Take the augmented matrix from the right side and call that the inverse The calculator will perform symbolic calculations whenever it is possible. If $$AN= I_n$$, then $$N$$ is called a right inverse of $$A$$. given $$n\times n$$ matrix $$A$$ and $$B$$, we do not necessarily … The inverse matrix, A^{-1}, is to the right of the augmented matrix If the matrix that corresponds to a principal minor is a quadratic upper-left part of the larger matrix (i.e., it consists of matrix elements in rows and columns from 1 to k), then the principal minor is called a leading principal minor (of order k) or corner (principal) minor (of order k). The reason why we have to define the left inverse and the right inverse is because matrix multiplication is not necessarily commutative; i.e. (I is the identity matrix), and a right inverse is a matrix R such that A R = I.
