## These two functions take a square matrix object and calculates its inverse. Once the inverse is calculated
## it is stored in a cache so that future calls for the solution matrix don't have to be recalculated.
## Takes a matrix object and attaches four functions: set, get, setsolve, and getsolve
## that allow the inverse matrix to be cached and recalled.
makeCacheMatrix <- function(x = matrix()) {
m <- NULL
set <- function(y) {
x <<- y
m <<- NULL
}
get <- function() x
setsolve <- function(inv) m <<- inv
getsolve <- function() m
list(set = set, get = get,
setsolve = setsolve,
getsolve = getsolve)
}
## Takes the matrix object and functions created by makeCacheMatrix. It check to see if an inverse matrix
## has already been cached. If it has, it returns the cache matrix with a message that it is cached data.
## If the solution hasn't been cached, the function returns the inverse matrix and stores it to the cache.
cacheSolve <- function(x, ...) {
## Return a matrix that is the inverse of 'x'
m <- x$getsolve()
if(!is.null(m)) {
message("getting cached data")
return(m)
}
data <- x$get()
m <- solve(data, ...)
x$setsolve(m)
