Simplifying the previous adjoint matrix results.
[Click here for a PDF version of this (and the previous) post] We previously found determinant expressions for the matrix elements of the adjoint for 2D and 3D matrices \( M \). However, we can extract additional structure from each of those results. 2D case. Given a matrix expressed in block matrix form in terms of it’s columns \begin{equation}\label{eqn:adjoint:500} M = \begin{bmatrix} \Bm_1 &…
