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 WebMar 24, 2024 · The conjugate transpose is also known as the adjoint matrix, adjugate matrix, Hermitian adjoint, or Hermitian transpose (Strang 1988, p. 221). Unfortunately, several different notations are in use as summarized in the following table. While the notation is universally used in quantum field theory, is commonly used in linear algebra.
