![]() ![]() Then you compute the cofactors, and then, you transpose the cofactors to get the adjoint. So, in order to make it easier to remember we have broken-down the adjoint formula into 3 steps: First, you compute the matrix of minors, Simple! Once you have the cofactor matrix calculated already, the you need to transpose The cofactor matrix, \(C\) is obtained from the minors by adding certain "signs", and defined as:įinally, how do you get to the adjoint matrix? What is the adjoint formula? But in college math, the only times you will likely stumble upon the adjoint is when you compute the inverse of a matrix using the adjointįirst, in terms of how adjoint of a matrix is calculated, let us recall the minors matrix which is computed by calculating the determinant of the sub-matrices formed by removing the i-th row and j-th column of the given In all fairness, the concept of adjoint of a matrix plays a very important role in advanced math (where instead of matrices we deal with linear Indeed, the inverse matrix and the adjoint ![]() Same way as cofactors, the adjoint matrix is tightly associated with the inverse of a matrix. ![]() More about this adjoint matrix calculator. ![]()
