MATLAB: Strcmpi not returning 1

Question

% So I'm trying to find overlap between two strings. I am trying to use a logical index but compare never returns 1, any suggestions?
function [ combined, overlap ] = AssembleSeqs(left, right)
combined=[];
overlap=[];
shorter= min(length(left), length(right))
tester=[1:shorter];
for i=1:1:shorter
tester(i)=0;
leftend=left(end-i+1)
rightend=right(i)
compare=strcmpi('leftend','rightend')
if (compare==1)
    tester(i)=1;
end

Answer 1

You need compare string from 2 variables leftend and rightend, but you are comparing 2 string 'leftend' , 'rightend'.

Let remove apostrophe and sure about 2 variables leftend and rightend are string
