Question: Write a function catit1 that will receive one input argument, which is a cell array. If the cell array contains only strings, it will return two strings : one string is all of the strings from the cell array concatenated together, the other string is combing the last alphabets of each word in cell array. Otherwise, it will return two empty strings.

>>fishies={‘tuna’, ‘shark’, ‘salmon’}
>>[str1,str2]=catit1(fishies)
str1= ‘tunasharksalmon’ 
str2= ‘akn’

I am having trouble figuring out how to get the strings to both concatenate and encrypt. Without the str2 input at the bottom, the str1 concatenation works fine.

fishies = {'tuna','shark','salmon'};
[str1,str2] = catit1(fishies);

function [str1,str2] = catit1(ca)
    str1 = '';
    if iscellstr(ca)
        for i = 1:length(ca)
            str1 = strcat(str1,ca{i});
        end
    end
    car = char(ca);
    rest = strtrim(car);
    str2 = '';
    while ~isempty(rest)
        [word,rest] = strtok(rest);
        str2 = strcat(str2,word(end));
    end
end

Simpler without loops:

>> C = {'tuna','shark','salmon'};
>> horzcat(C{:}) % comma-separated list
ans = tunasharksalmon
>> cellfun(@(v)v(end),C)
ans = akn
