Please code in MATLAB in possible. I am very curious how this works but my coding knowledge is not sufficient enough to perform it

Problem 1. (Design and Program) Design and implement a block cipher based on Feistel Cipher. Please see the requirements as follows: Determine the important components before implementation a. Block size: 64-bit is recommended, you are free to choose any block size no smaller than 64 bits. b. Key size: 128-bit is recommended, you are free to choose any block size no less than 64 bits. c. Number of rounds: you can pick it on your own. d. Subkey generation algorithm: design an algorithm to generate subkeys based on the secret key. e. Round function: design a round function which takes in the right half of the input and the subkey. Implement your block cipher f. Show a demo by doing one encryption i. The input is one block of all is (i.e., 64-bit 111111.... if your block size is 64-bit). ii. The secret key is set as all 1s.(i.e., 111111...) g. Do the decryption correspondingly. Problem 1.
