Need help with rgb image

Aaron - this seems like homework, so please show us what you have tried so far. Discuss your code and the problems and/or errors that you are observing.

I’m not sure how to do the second part to get the image to display from -1m 5m and -5m

[Geoff Hayes]

Please attach your code rather than screen shots to the code. Also, attach the mat file rather than a link to i.
