cachematrix.R

## Below functions compute inverse of a matrix and cache the result
## As per the assignment, the matrix supplied must be invertible 

## 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)

}


## This function computes the inverse of the special "matrix" returned by makeCacheMatrix above
## If the inverse has already been calculated (and the matrix has not changed), then the cachesolve should retrieve 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
