Calculating adjoint of a matrix

The formula for the adjoint of a matrix can be derived using the cofactor and transpose of a matrix. However, it is easy to find the adjugate matrix for a 2 x 2 matrix. Let’s have a look at the formulas and procedure of finding the adjoint matrix for a given matrix. See more It is necessary to find the adjoint of a given matrix to calculate the inverse matrix. This can be done only for square matrices. Click here to understand what a square matrixis. See more Let A be the 2 x 2 matrix and is given by: Then, the adjoint of this matrix is: Here, A11 = Cofactor of a11 A12 = Cofactor of a12 A21 = Cofactor … See more Example 1: Solution: Here, a11 = 2, a12 = 3, a21 = 1 and a22= 4. So the cofactors are: A11 = a22= 4 A12 = -a12= -3 A21 = -a21= -1 A22 = a11= 2 Example 2: Solution: Let Cij be the cofactor of the element aijin matrix … See more Consider a 3 x 3 matrix as: The adjugate of this matrix is given by: Here, The above formula can be expanded as: Alternatively, we can find the cofactors of the matrix using the formula, Cofactor of the element aij = Cij = (−1)i+j … See more WebFirst, verify the following calculation where the matrix A above is multiplied by its adjoint: Now, since a Laplace expansion by the first column of A gives equation (*) becomes. This result gives the following equation for the inverse of A: By generalizing these calculations to an arbitrary n by n matrix, the following theorem can be proved ...
