Simple CRC calculator and veifier

Simple program that calculates crc for a 7 bit binary data using a 4bit crc polynomial.

type "untitled" to run.

The 7 bit data can be inputted or generated randomly.The crc polynomial used is fixed and cant be changed.
The function that calculates and verifies the crc is " mycrc ".
The file untitled is the gui but its m file also contains code for generation of random data.

Iv included the pseudo code in the zip file.

Made this program last year as part of an assignment.
Hope it proves to be of some use.
