Additional features of the inverse matrix calculator
Theory. Inverse matrix.
Definition.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
Use matrix of cofactors to calculate inverse matrix
Definition.Matrix C, elements of which are the cofactors of the corresponding elements of the matrix A is called the matrix of cofactors.
Definition.Transpose of the matrix of cofactors, known as an adjugate matrix.
