cachematrix.R

## Two functions used for cached matrix inversion calculating.

## Function creates matrix with ability to cache its inversed value.
makeCacheMatrix <- function(x = matrix()) {
  inv <- NULL
  set <- function(y) {
    x <<- y
    m <<- NULL
  }
  get <- function() x
  setInverse <- function(inverse) inv <<- inverse
  getInverse <- function() inv
  list(set = set, get = get,
       setInverse = setInverse,
       getInverse = getInverse)
}

## Function calculates inverse of matrix if it hasn't been cached.
## It it has already been cached, function will return cached value.
cacheSolve <- function(x, ...) {
  inverse <- x$getInverse()
  if(!is.null(inverse)) {
    message("getting cached data")
    return(inverse)
  }
  data <- x$get()
  inverse <- solve(data, ...)
  x$setInverse(inverse)
  inverse
}
