makeVector <- function(x = numeric()) { m <- NULL set <- function(y) { x <<- y m <<- NULL } get <- function() x setmean <- function(mean) m <<- mean getmean <- function() m list(set = set, get = get, setmean = setmean, getmean = getmean) }

A pair of functions that cache the inverse of a matrix.

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(solveMatrix) inv <<- solveMatrix 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.

cacheSolve <- function(x, ...) {

Return a matrix that is the inverse of 'x'

inv <- x$getInverse() if(!is.null(inv)){ message("getting cached data") return(inv) } data <- x$get() inv <- solve(data) x$setInverse(inv) inv
}
