Your code has no documentation as to what it is intended to calculate, so as outside volunteers looking at it with no knowledge of purpose, we must assume that the code is correct and that you are mistaken about the code being wrong.

It is my understanding that only the letters in the string input must be changed according to the logic of the script and other characters be retained. You may use the below script to achieve this:
function coded = hw5_problem1(txt)
coded = txt;
small = isstrprop(txt,'lower');
big = isstrprop(txt,'upper');
coded(small) = char(219-txt(small));
coded(big) = char(155-txt(big));
Hope this helps!
