'makeCacheMatrix' creates a special "matrix" object while 'cacheSolve' function computes the inverse of the special "matrix" returned.

'makeCacheMatrix' creates a special "matrix" object that can cache its inverse.

makeCacheMatrix <- function(x = matrix()) { int <- NULL set <- function(a) { dig <<- a int <<- NULL } get <- function() dig setinverse <- function(inverse) int <<- inverse getinverse <- function() int list(set = set, get = get, setinverse = setinverse, getinverse = getinverse) }

'cacheSolve' function computes the inverse of the special "matrix" returned by makeCacheMatrix above and

if the inverse has already been calculated (and the matrix has not changed),

then cacheSolve retrieve the inverse from the cache.

cacheSolve <- function(dig, ...) { int <- int$getinverse() ## Return a matrix that is the inverse of 'dig' if(!is.null(int)) { message("getting cached data") return(int) } else{ data <- dig$get() int <- mean(data, ...) dig$setinverse(int) int } } cachematrix.txt

This is not the way you should submit your assignment.

Yeah, I submitted again in the correct way. Thanks. On 5 Feb 2016 21:29, "Raphael R." notifications@github.com wrote:
