Inverse of a matrix using minors cofactors and adjugate note.
Adjoint of 3x3 matrix formula.
The adjoint of a matrix a is the transpose of the cofactor matrix of a.
To find the inverse of a 3 by 3 matrix is a little critical job but can be evaluated by following few steps.
For example if a problem requires you to divide by a fraction you can more easily multiply by its reciprocal.

The adjoint of 3x3 matrix block computes the adjoint matrix for the input matrix.
When a is invertible then its inverse can be obtained by the formula given below.
This is an inverse operation.

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.
It is also occasionally known as adjunct matrix though this nomenclature appears to have decreased in usage.

In linear algebra the adjugate or classical adjoint of a square matrix is the transpose of its cofactor matrix.
Let a be a square matrix of order n then the matrix of cofactors of a is defined as the matrix obtained by replacing each element aij of a with the corresponding cofactor aij.
