WebFAMILIAR OPERATORS Up: Table of Contents Adjoint operators A great many of the calculations we do in science and engineering are really matrix multiplication in disguise. The first goal of this chapter is to unmask the disguise by showing many examples. Second, we will illuminate the meaning of the adjoint operator (matrix transpose) in these many … 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 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 … 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 of a21 A22 = Cofactor of a22 Alternatively, the adj A can also be calculated by … 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 … 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, … 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.
