Using the function

makeCacheMatrix returns a list of functions that enable the user to:

• set the value of the vector
• get the value of the vector
• set the value of the mean
• get the value of the mean

The input for makeCacheMatrix must be a square matrix.

cacheSolve returns the inverted matrix. When already cached, it retrieves from the cache. Else, it will compute a new inverted matrix.

Example input:

exampleVector <- seq(1:4)

exampleMatrix <- matrix(exampleVector, 2)

exampleCacheMatrix <- makeCacheMatrix(exampleMatrix)

cacheSolve(exampleCacheMatrix)

Example output:

 [,1] [,2]
 
[1,]   -2  1.5

[2,]    1 -0.5
