Inverse of a Matrix using Minors, Cofactors and Adjugate Minors and Cofactors Minor of an element: If we take the element of the determinant and delete (remove) the row and column containing that element, the determinant left is called the minor of that element. It is denoted by Mij. Similarly, we can find the minors […]

A coefficient matrix can only have an inverse if the system of equations it represents has a unique solution. If the determinant of the matrix is zero, then it will not have an inverse; the matrix is then said to be singular. Only non-singular matrices have inverses.
