## Put comments here that give an overall description of what your
## functions do
## Write a short comment describing this function
## This function creates a special "matrix" object that can cache its 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)
}
## Write a short comment describing this function
## This function computes the inverse of the special "matrix" returned by makeCacheMatrix. If the inverse has already been calculated (and the matrix has not changed), it retrieves the inverse from the cache.
cacheSolve <- function(x, ...) {
inv <- x$getInverse()
if (!is.null(inv)) {
message("getting cached data")
return(inv)
}
data <- x$get()
inv <- solve(data, ...)
x$setInverse(inv)
inv
## Return a matrix that is the inverse of 'x'
