## The following functions cache the inverse of a matrix.
## "makeCacheMatrix" creates the functions to cache the inverse of a matrix.
makeCacheMatrix <- function(x=matrix()) {
m <- NULL
set <- function(y) {
x <<- y
m <<- NULL
}
get <- function() x
setInverse <- function(inverse) m <<- inverse
getInverse <- function() m
list(set = set, get = get,setInverse = setInverse,getInverse = getInverse)
}
## "cacheSolve" calculates the inverse of the matrix returned from makeCacheMatrix().
## If the inverse matrix has already been calculated, it is retrieved from the cache.
cacheSolve <- function(x, ...) {
m <- x$getInverse()
if (!is.null(m)) {
print("getting cached data")
return(m)
}
m <- solve(x$get())
x$setInverse(m)
m
