## The function creates a new instance of the matrix with the getter and setter properties for a input matrix.
## set() and get() allows you to access cached values,i.e. the input matrix.
## setInverse and getInverse methods provides the access to cached inverse value of the input matrix.
## makeCacheMatrix: This function creates a special “matrix” object that can cache its inverse.
## The following functions are used to create a special object that stores a matrix and caches its inverse. 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
#get the value of the inverse
makeCacheMatrix <- function(x = matrix()) {
m <- NULL
set <- function(y) {
x <<- y
m <<- NULL
}
get <- function() x
setInverse <- function(inverse) m <<- inverse
getInverse <- function() m
list(set = set, get = get,
setInverse = setInverse,
getInverse = getInverse)
}
## cacheSolve: This function computes the inverse of the special “matrix” returned by makeCacheMatrix above.
## If the inverse has already been calculated (and the matrix has not changed),
## then the cachesolve should retrieve the inverse from the cache.
cacheSolve <- function(x, ...) {
## Return a matrix that is the inverse of 'x'
m <- x$getInverse()
if(!is.null(m)) {
message("getting cached data")
return(m)
}
data <- x$get()
m <- solve(data, ...)
x$setInverse(m)
m
}
