WebTo find the adjoint of a matrix, first replace each element in the matrix by its cofactor and then transpose the matrix. Remember that the formula to compute the i, j cofactor of a matrix is as follows: Where M ij is the i, j minor of the matrix, that is, the determinant that results from deleting the i-th row and the j-th column of the matrix. WebIn mathematics, the term adjoint applies in several situations. Several of these share a similar formalism: if A is adjoint to B, then there is typically some formula of the type. ( Ax, …
