In the previous article, you learned about Inverse of Matrix and why it is important. We will explore how to find inverse of a matrix in this article. There are two primary method of finding inverse of any square invertible matrix – Classical adjoint method and Gauss -Jordan elimination method.
Methods To Find Inverse Of Matrix
The primary method of finding of inverse of matrix are
- Classical adjoint method
- Gauss-Jordan elimination method
Throughout this article, we will discuss about these two methods in detail.
Classical Adjoint Method
If is an invertible matrix then we can find the inverse of matrix with the adjoint of matrix .
But,before we begin you must understand a few terminologies.
Determinant – It is a special number obtained from a Square Matrix, non-square matrix do not have determinants. If is a square matrix then there is a number of ways to denote its determinant.
Minor of a matrix – The minor of a square matrix is determinant obtained by deleting a row and a column from the determinant of a larger square matrix. It is denoted by for element where is the ithrow and is the jth column.
