Although the inverse of a $3 \times 3$ order matrix is more complicated as compared to the $2 \times 2$ order matrix, it can be calculated mathematically. History of Jacobian Matrix The concept of the Jacobian Matrix was introduced by the $19^{th}$ century mathematician and philosopher Carl Gustav Jacob Jacobi. As per the definition of additive inverse property, the additive inverse of number A states as A + (-A) = 0. If we take X as a number and Y as an additive inverse number then add both and the result should be zero. ie., X+Y=0. Then, Y = -X. So, the additive inverse of the number is -X. Also, we can define the additive inverse is the opposite of. An inverse of a matrix is basically 1 over that matrix. Say we have a matrix called A, then the inverse of A is 1⁄A, it is also denoted by . Unfortunately you can’t just do one over every element in the matrix to get the inverse, it takes a little more work than that. It’s simple enough in a 2×2 matrix, so I’ll demonstrate it with that. 1 Inverse of a square matrix An n×n square matrix A is called invertible if there exists a matrix X such that AX = XA = I, where I is the n × n identity matrix. If such matrix X exists, one can show that it is unique. We call it the inverse of A and denote it by A−1 = X, so that AA −1= A A = I holds if A−1 exists, i.e. if A is. The adjoint of a scalar multiplication is equal to the product of the scalar raised to n-1 and the adjoint of the matrix, where n is the order of the matrix. Let A be a square matrix of order n, if the rank of matrix A is less than or equal to n-2, then the adjoint of matrix A results in 0. Let A be a square matrix of order n, if the rank of.
