use matlab or octave to code. DO NOT USE if statements, while or for loops, reshape commands. Only use vectors, matrices, functions, or strings.

3. (Basic ASCII Caesar Cipher) A very ancient cryptographic technique for hiding a message was to use a Caesar Cipher where each letter of a message is shifted down the alphabet (i.e. towards later letters) by a fixed amount. Normally, if a letter falls off the end of the alphabet it should wrap back onto the beginning. For this problem, we will consider a very basic implementation of such a cipher, were we do not worry about this wrapping. basic_caesar Function: Input variables: a string representing the message to be encoded a scalar representing the "key" (the amount to shift by) Output variables: a string representing the encoded message (note: you will have to force the result of your computations to be a character string by using the function char( applied to your resulting message) . A possible sample case is: >> ciphertext = basic caesar ('MATHRULES', 6) ciphertext = SGZNX (RKY
