How can i write a MATLAB function named dedbi that takes input xtx as string and returns another string xtxx as output.

Question

dedbi reverse the words that is, ‘a’ will be replaced by ‘z’, ‘b’ will be replaced by ‘y’, ‘c’ will be replaced by ‘x’ and so on. dedbi will do the same for capital letter t

Answer 1

Pseudo code:

function out = func_name(in)
    in = array of ascii values from original in values (can be done with one command)
    out = vector if zeros the size of in (one command)
    loop through all numbers of in
        ch = current char ascii value (just because it is easier to write ch than in(index) in my opinion)
        if ch is btw 65 and 96
            subtract 65 so ch is 1-26
            find 26-ch (invert)
            add 65 so ch is 65-96
        if ch is btw  97 and 122
            do the same as above with adjusted numbers
        end if
        out(index_of_for_loop) = ch
    end loop
end function

Note: In general, it is best to avoid code that has many copy-paste section because it can be difficult to edit quickly.
