## These two functions together calculate the inverse of a matrix without performing unnecessary calculations,
## minimizing computation time.
## Write a short comment describing this function
## 1. Set the value of the matrix
## 2. Get the value of the matrix
## 3. Set the inverse of the matrix
## 4. get the inverse of the matrix
