*3x3 Inverse Matrix Calculator* is an online tool programmed to calculate the Inverse of given 3x3 matrix input values

### What is Inverse Matrix?

An Inverse Matrix is a matrix that when multiplied by the original matrix yields the identity matrix. The inverse of a square n x n matrix A, is another n x n matrix denoted by A^{-1} such that

**A A**^{-1} = A^{-1} A = I

where I is the n x n identity matrix. That is, multiplying a matrix by its inverse produces an identity matrix. Not all square matrices have an inverse matrix. If the determinant of the matrix is zero, then it will not have an inverse, and the matrix is said to be singular. Only non-singular matrices have inverses
