The inverse matrix formula is used to determine the inverse matrix for any given matrix. The inverse of a matrix is one of the important operations, applicable only for a square matrix. The inverse of any matrix is denoted as the matrix raised to the power (-1), i.e. for any matrix "A", the inverse matrix will be denoted as A-1. The inverse of a square matrix, A is A-1 only when: A × A-1 = A-1 × A = I. There is a possibility that sometimes inverse operation might not exist for a matrix. Let us understand the inverse matrix formula in the following section.
