## Put comments here that give an overall description of what your
## functions do
## First part of the function will make cache matrix which will get and set the value
## of the matrix and get and set the value of the inverse.
makeCacheMatrix <- function(x = matrix()) {
i <- NULL
set <- function(y) {
x <<- y
i <<- NULL
}
# get the value of the matrix
get <- function() x
# set the value of the inverse
setinverse <- function(inverse) i <<- inverse
# get the value of the inverse
getinverse <- function() i
list(set = set,
get = get,
setinverse = setinverse,
getinverse = getinverse)
}
## The following function returns the inverse of the matrix. It checks if
## the inverse has already been computed. If yes, it gets the result and skips the
## computation. If not, it computes the inverse, sets the value in the cache via
## setinverse function.
cacheSolve <- function(x, ...) {
i <- x$getinverse()
if (!is.null(i)) {
message("getting cached data")
return(i)
}
data <- x$get()
i <- solve(data, ...)
x$setinverse(i)
i
}
## Test
#B <- matrix(c(1,3,5,7),2,2)
#B1 <- makeCacheMatrix(B)
#cacheSolve(B1)
