Is there a function in MATLAB that uses the method of Attachment?

I am doing a homework on solution of matrix and I want to use MATLAB to corroborate my reasoning.

My native language is spanish and I don't know how to search this formula in MATLAB since I don't know its name in english.

The formula goes as follows,

 [A]^(-1) = {[A^d]^T}/det[A] % where [A] is a 4 x 4 matrix and [A^d] is the method of attachment, translated from spanish

Has anyone seen some function or code in MATLAB related to this formula?

Thank you for your time.

[A^d] seems to refer to the cofactor matrix. The tranpose of the cofactor matrix [A^d]^T is the adjugate matrix.

Here is a FEX file claiming to compute the adjugate

I haven't used the file myself, but I do trust its author!
