cachematrix.R

## Module that implements calculating of matrix inverse and
## caching of the inverse for future re-use without need to calculate it again

## Creates a special "matrix" object that can cache its inverse.
makeCacheMatrix <- function(x = matrix()) {
  s <- NULL
  set <- function(y) {
    x <<- y
    s <<- NULL
  }
  get <- function() x
  setsolve <- function(solve) s <<- solve
  getsolve <- function() s
  list(set = set, get = get,
       setsolve = setsolve,
       getsolve = getsolve)
  
}


## 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  cacheSolve  should retrieve 
## the inverse from the cache.

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