## Below are two functions that are used to create a special object that stores a matrix and cache's its inverse
##
## Write a short comment describing this function
##The first function, makeCacheMatrix creates a special "matrix", which is really a list containing a function to
## set the value of the matrix
## get the value of the matrix
## set the value of the inverse of matrix
## get the value of the imverse of matrix
makeCacheMatrix <- function(x = matrix()) {
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
##The following function calculates the inverse of the special "matrix"
##created with the above function. However, it first checks
##to see if the inverse has already been calculated. If so, it gets the inverse
##from the cache and skips the computation. Otherwise,
##it calculates the inverse of the data and sets the value of the
##inverse in the cache via the setsolve function.
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
}
