Cell array, string concatenation

*I'm trying to create a function that will concatenate the two input strings. If one of the strings is longer than the other, I should only concatenate the last N characters of the longer string, where N is the length of the shorter string. For example, if the input strings were 'Hello' and 'MATLAB' the output would be ' HelloATLAB'. 'Hello' is the shorter of the two words at 5 characters, so the last 5 characters of the other string are concatenated. The first input will always be concatenated in front of the second input.

So here's the start that I wrote.

function [str] = shortCat(in1, in2)

cin = {in1; in2};

Lin = [length(in1) length(in2)];

Ldif = abs(Lin(1)-Lin(2));

[~,Lmax] = max(Lin);

I'm lost after this. Can someone help me to solve this?

Danny, I would simply use an if-else for that, combined with indexing

 function [str] = shortCat(in1, in2)

 s1 = size(in1,2);
 s2 = size(in2,2);

 if s1 > s2
     str = [in1(s1-s2+1:s1), in2];
 else
     str = [in1, in2(s2-s1+1:s2)];
 end
 end

That's so much simpler than the way I was thinking. I should've used if-else loop from the start. Thank you so much!

function outString = myStringConcatenator(inString1, inString2)

   minLength = min(length(inString1), length(inString2));

   outString = [inString1(length(inString1)-minLength+1 : end) ...
               inString2(length(inString2)-minLength+1 : end)];

end
