How to do the following on MATLAB

Create the program similar to Practice problem P10.2 but it decode the input character string by subtracting 10 from decimal equivalent value of each character. Show a sample response for inputting your name as an input. For your reference, the MATLAB codes for Problem P10.2 are shown below 10 2m un Section Indent Practice problem 10.2 2A-input (Enter a string of information to be encoded: 3- Aencoded=char(A+5) ; %adding 5 to ASCII codes of all cha 4- 5- disp (Aencoded) ; 6disp ('Would you like to decode this message?') - disp 'Your input has been encoded:) response-menu ('yes or no?', 'YES ,'NO) 8Switch response case 1 10 disp (char (A encoded-5)) case 2 disp ('OK Goodbye) 13-end
