What is the inverse of a matrix product?
5. inverse of a matrix product: inv(A * B) = inv(B) %*% inv(A) This extends to any number of terms: the inverse of a product is the product of the inverses in reverse order.What is inverse product?
Let A,B?Fn×n where F denotes a field and n is a positive integer. Let C=AB. If A and B are both invertible, then C is invertible and C?1 is given by B?1A?1. (How to find the inverse of a matrix as a product of elementary matrices?
In fact, the inverse of an elementary matrix is constructed by doing the reverse row operation on I. E?1 will be obtained by performing the row operation which would carry E back to I. If E is obtained by switching rows i and j, then E?1 is also obtained by switching rows i and j.- What is the Inverse of 3x3 Matrix? 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??? [ 1 0 0 0 1 0 0 1 0 ] .
