The adjugate of an n × n matrix A is the transpose of the cofactor matrix of A. Thus, if we designate the adjugate of A by Aa, we have that Aa = (Ac)T. Example 2 Find Aa for the A given in Example 1. Solution Aa=[180−61616−6−11−817].■ The importance of the ...
👉 If you ever need to calculate the adjoint (aka adjugate) matrix, remember that it is just the transpose of the cofactor matrix of A. Learn more in the adjoint matrix calculator. Cofactor matrix 2×2 As an example, let's discuss how to find the cofactor of the 2 x 2 matrix: [...
