\examples{
## First, create the matrix cache:
q<-makeCacheMatrix(matrix(c(0,1,2,0),nrow=2))

## Then call the first time, normal executino time
cacheSolve(q)
     [,1] [,2]
[1,]  0.0    1
[2,]  0.5    0
> 
> # Finally, call a second time.
> # 'getting cached data' should be printed!
> cacheSolve(q)
getting cached data
     [,1] [,2]
[1,]  0.0    1
[2,]  0.5    0
