MATLAB是一种以数值计算和数据图示为主的计算机软件，并包含适应多个学科的专业软件包，以及完善程序开发功能。 本课程设计旨在要求学生熟悉Matlab的功能，掌握Matlab程序设计和GUI设计的方法，培养学生的应用开发能力，为以后的毕业设计奠定一定的基础。(MATLAB is a numerical calculation and data icon-based computer software, and includes a number of disciplines to adapt to the package, as well as improve the development function. This course is designed to require students to know the function of Matlab, master Matlab programming and GUI design methods, and foster the application of student development capacity, for future graduation project to lay a foundation.)

Data Encryption by Matrix Multiplication We will only use numbers 0 to 26 for the encryptive mathematics operation. Numbers from 1 to 26 are for letters from A to Z and 0 is for all non-letter characters. To minimize usage of numbers, all letters are converted to upper case. The original message is converted to number array according to the ASCII table and minus 64. We partition whole array into blocks of 8 numbers. The last block may be added several zeros. Then multiply each block by the an 8x8 matrix A which is invertible in Z27 to get cipher data. The decryption is the same process except to use its inverse matrix B. For good visual reading, we convert all non-letter characters to under score for the decryption.
