## Put comments here that give an overall description of what your
## functions do
## Write a short comment describing this function
## Creates an opbect of type list that acts as a storage device.
## Stores the original matrix value and what will be the solve which is set to null
## This is essentially a getter setter to put it into OOP terms I am familier with
makeCacheMatrix <- function(x = matrix()) {
s <- NULL #set 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)
}
## Write a short comment describing this function
## Accesses the makeCacheMatrix object (not the function).
## Gets the value of the matrix used to create the object.
## If solve has not been calculated then it calculates and stores it
## If it has been calculated it gets and returns the value
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
}
