It is also occasionally known as adjunct matrix though this nomenclature appears to have decreased in usage.
Adjoint of 3x3 matrix formula.
To find the inverse of a 3 by 3 matrix is a little critical job but can be evaluated by following few steps.
Inverse of a matrix using minors cofactors and adjugate note.

Find the adjoint of the matrix.
For example if a problem requires you to divide by a fraction you can more easily multiply by its reciprocal.
Finding adjoint of a matrix examples.
The adjugate has sometimes been called the adjoint but today the adjoint of a matrix normally refers to its corresponding adjoint operator which is its conjugate.
In linear algebra the adjugate or classical adjoint of a square matrix is the transpose of its cofactor matrix.
How to find adjoint of a matrix.
An adjoint matrix is also called an adjugate matrix.
Calculating the inverse of a 3x3 matrix by hand is a tedious job but worth reviewing.
Then turn that into the matrix of cofactors.
We can calculate the inverse of a matrix by.
The matrix adj a is called the adjoint of matrix a.
The inverse is defined only for non singular square matrices.
Similarly since there is no division operator for matrices you need to multiply by the inverse matrix.
A singular matrix is the one in which the determinant is not equal to zero.
Calculating the matrix of minors step 2.

The adjoint of a matrix a is the transpose of the cofactor matrix of a.
Elements of the matrix are the numbers which make up the matrix.
A 3 x 3 matrix has 3 rows and 3 columns.
It is denoted by adj a.
