## Put comments here that give an overall description of what your
## functions do
## Write a short comment describing this function
##For this assignment, assume that the matrix supplied is always invertible.
##This function creates a special "matrix" object that can cache its inverse.
makeCacheMatrix <- function(x = matrix())
{
m <- NULL
set <- function(y) {
x <<- y
m <<- NULL
}
get <- function() x #get value of matrix provided as argument
getInverse <- function() m #get value of inversed matrix
setInverse <- function(inverse_matrix) m <<-inverse_matrix #set value of matrix to inverse value
list(set = set, get = get,
setInverse = setInverse,
getInverse = getInverse)
}
## Write a short comment describing this function
##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$getInverse()
if ( ! is.null(m)) {
print("getting cached data")
return(m)
}
m <- solve(x$get()) #Computing the inverse of a square matrix can be done with the solve function in R.
#For example, if X is a square invertible matrix, then solve(X) returns its inverse.
x$setInverse(m) #update value of m in makeCacheMatrix function
