## These are two functions used to create objects to store a matrix and
## cache its inverse. These functions make use of the <<- operator which
## is used to assign a value to an object that is in a different from the
## current environment
## Creates a Cache Matrix Object. This is actually a list containing functions to:
## set the matrix, get the matrix, set the inverse, get the inverse
makeCacheMatrix <- function(x = matrix()) {
inv <- NULL
set <- function(y) {
x <<- y
inv <<- NULL
}
get <- function() x
setinverse <- function(inverse) inv <<- inverse
getinverse <- function() inv
list(set = set, get = get,
setinverse = setinverse,
getinverse = getinverse)
}
## This function computes the inverse of x and stores it in a Cache Matrix object.
## If the inverse was previously computed, use the cached result.
## The inverse is returned
