## Put comments here that give an overall description of what your

## Write a short comment describing this function

## Write a short comment describing this function
## cacheSolve is a function which computes the inverse of the special "matrix"
## returned by makeCacheMatrix above. If the inverse has already been calculated

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