The Figure 26 shown above demonstrates my design and thinking process for Task 3.  We needed 2 inputs for the code: One was the Somerton Man code which is the encoded message, other was the letter position as the ''key'' (the range of the letter position is above 0 and starts with integer 1 based on the MATLAB system). The function was to output a letter from the Somerton Man code and a number n from the letter position. Then, a function called matching was then to receive the letter output from the Somerton Man code. It was to search the ''Rubaiyat'' from beginning to end to match the first word with the same initial letter. At the same time, a function called finding was to receive the number output by letter position. Afterwards, the function matching was to send the matched word from ''Rubaiyat'' to the function 'finding'. This function was then to choose the correct letter in the matched word based on the letter position n. For example, if n equaled to 2, the 'finding' function would choose the second letter of the matched word. Finally, the function would output the chosen letter to a function called 'recordMessage', and this function would record all the letters from 'finding' in order. The program would have now completed decoding for one letter of Somerton Man code, and would then repeat for the rest of the letters in the code. After decoding all letters, the program would output the original message.
