We give the adjugate matrix formula and explain how to find the adjugate matrix of size 2x2 via this formula. What is the adjoint of a matrix (adjugate matrix)? First of all, be aware that what we call the adjoint matrix here is sometimes called the adjugate matrix. You may also ...

We denote by / the 4x4 identity matrix, which at times implies the 2x2 identity matrix, but no confusion will occur. For a closable operator T in JC, we denote by T its closure. For an (formal) operator T, we denote by T the restriction of T to the domain 展开 ...
