Sample run of cachematrix.R

The following R terminal output shows two calls to cacheSolve(). In the first call, the inverse of m_cache must be calculated. In the second call, the cached value is retrieved.

> m = matrix(c(4,3,3,2), 2, 2)
> m
     [,1] [,2]
[1,]    4    3
[2,]    3    2
> m_cache <- makeCacheMatrix(m)
> cacheSolve(m_cache)
     [,1] [,2]
