How do you invert a 4x4 matrix?
How do you find the inverse of a 4x4 matrix? The inverse of a square matrix can be found through row reduction of the augmented matrix, created by attaching a copy of the identity matrix. If the matrix can be reduced to the identity, then in parallel the identity matrix will transform to the inverse matrix.25 jan. 2022- The inverse of a 3x3 matrix, say A, is a matrix of the same order denoted by A-1 where AA-1 = A-1A = I, where I is the identity matrix of order 3x3. i.e., I = ???100010010???
