cachematrix.R

## These 2 functions are used to store computed inverse matrix as a cache

## This function creates a special matrix object that can cache its inverse

makeCacheMatrix <- function(x = matrix()) {
  res <- NULL
  set <- function(y) {
    x <<- y
    res <<- NULL
  }
  get <- function() x
  setinv <- function(result) res <<- result
  getinv <- function() res
  list(set = set, get = get,
       setinv = setinv,
       getinv = getinv)
}


## This function computes the inverse of the special matrix returned above

cacheSolve <- function(x, ...) {
        ## Return a matrix that is the inverse of 'x'
  res <- x$getinv()
  if(!is.null(res)){
    message("getting cached data")
    return(res)
  }
  
  data <- x$get()
  res <- solve(data, ...)
  x$setinv(res)
  res
}
