Inverse matrix A⁻¹ is the matrix, the product of which to original matrix A is equal to the identity matrix I:

A·A^-1 = A^-1·A = I

Matrix C, elements of which are the cofactors of the corresponding elements of the matrix A is called the matrix of cofactors.

Transpose of the matrix of cofactors, known as an adjugate matrix.
