Using Matlab:

Finally, write a script entitled decodeM essage.m that takes your image and decodes the message. This script should be able to read in an image file that has an encoded message from your hiddenM essage.m script and print out the decoded message. You will need to save your image file (this should be done in your hiddenM essage.m script) as either a .png or full quality .jpg. You can assume that the users message will fit inside of just the number of rows. However, you should try to handle exiting the scan early or avoid appending spaces to the end of the decoded message. How exactly you do this will be left up to you to decide, but feel free to ask a TA if you are uncertain about your approach or how to go about the problem.
