The matrix of cofactors is a type of square matrix that is computed from an original square matrix. It is achieved by substituting every element with its corresponding cofactor. The cofactor matrix plays a crucial role in calculating matrix inversions and determinants. In order to obtain the cofactor matrix, one must first determine the cofactor of each individual element, then organize these cofactors into a matrix that mimics the structure of the initial matrix.
