## Matrix inversions might be computational differnt, especially with
## large matrices. These functions will cache the inverse when it has been
## computed. Every time it will check beforehand if the matrix
## has been inverted before. If so, the inverse will be caught from cachhe.
## makeCacheMatrix creates a special object that stores a matrix and caches
## its inverse
## The value of the matrix is set and can be gotten
## The value of the inversie is set and can bet gotten
makeCacheMatrix <- function(x = matrix()) {
m <- NULL
set <- function(y){
x <<- y
m <<- NULL
}
get <- function()x
setInverse <- function(solve) m <<- solve
getInverse <- function() m
list(set = set, get = get,
setInverse = setInvervse
getInverse = getInverse)
}
## cacheSolve computes the inverse of special "matrix" from makeCacheMatrix. When it was
## calculated before, it will get the inverse from the cache and skips the computation.
cacheSolve <- function(x, ...) {
## Return a matrix that is the inverse of 'x'
m <- x$getInverse()
if(!is.null(m)){
## Matrix was inverted before and result will be gotten from cache
message("getting cached data")
return(m)
}
data <- x$get()
## Matrix was not inverted before, computation will be done now
m <- solve(data, ...)
x$setInverse(m)
m
}
You can’t perform that action at this time.
